Currently, handling of touch devices in the app grid is a bit awkward,
paging by dragging the view can only happen if started from the gaps
between icons, trying to drag from an icon will trigger DnD, and popping
up the menu takes over it all.
Instead, have the app grid actions play this game of rock-paper-scissors:
- Fast swipes on icons trigger scrolling, beats DnD and menu
- Slower press-and-drag on icons trigger DnD, beats scrolling and menu
- Long press triggers menu, beats scrolling, is beaten by DnD
This allows quick swipes to handle navigation, while still allowing the
fine grained operations. DnD, when triggered, dismisses the menu, if
shown.
This all could probably be nicer with a more stateful gesture framework,
we're not there yet though.

This setting (by default, 0) sets a time threshold in order to allow
DnD. If the drag is shorter than this threshold, DnD will be cancelled,
and event handling left to the next handlers.

The switcherPopups use _next() and _previous() to get the items
in the text direction. I. e. with LTR _next() gets the right item;
on RTL it gets the left item. This doesn't work well with RTL when using
the arrow keys since the text direction doesn't matter in those cases.
Pressing Left Arrow should still move left regardless of text direction.
So use the opposite methods.

If for some reason the xserver failed to start, mutter/gnome-shell
should not attempt to connect to the X11 display otherwise it will
lock up in XCB.
An indication of such a premature failure of the xserver is when the X11
services fail to start.
Return the status so that the caller can cancel the connection in time
and avoid the lockup of mutter/gnome-shell in case of failure.
This, however, makes the X11 services a critical component to start
Xwayland, meaning that a failure to start those services for any other
reason than the xserver failing to start would still prevent Xwayland
and therefore X11 clients to run in Wayland. This is however a lesser
issue than mutter/gnome-shell locking up.
This basically reverts commit a96753f0 - "windowManager: X11 can work

Previously the workarea was only set on construction and then never
updated. As a result the preferred width and height as well as the
allocation were based on an outdated workarea size when it changed after
construction. This for example was happening during the startup
animation, for which the WorkspaceLayout is constructed before the panel
is shown. This caused the workspace in the overview to be slightly
smaller when it is first shown and the overview closing animation to
not expand the workspace to the correct size the first time it is
closed.

In the nested session the startup animation sometimes fails, weirdly
that always happens to me when running a freshly built gnome-shell the
first time. The reason it fails is that mutter fails to aquire a pointer
grab from the xserver, XIGrabDevice() is unsuccessful.
A simple workaround for this race condition in the xserver is to just
grab the devices a bit later, that is after the startups animation
instead of before it.
This was also tested with disabled animations, and seems to work just as
well in that case.

Some drag actor parents might change their width to 0 after the drag
actor has been removed. If the drag is now canceled and the drag actor
is animated to return to the current parent position and scale, this
scale can not be determined and falls back to 1.0. This might be wrong
and can result in the drag actor being too large/small at the end of the
return animation.
To avoid this calculate the scale of the parent by recursively
calculating the product of its parents individual scales.

We want to clip the Workspace actor in the appGrid state of the overview
in order to make sure windows that overflow the monitor don't spill out.
So far we had commit b1970b95b8 for that.
Now since the last commit, window previews always slightly overflow the
allocation with their icons. That means a part of the window icon gets
clipped away as soon as the transition to the appGrid starts, which
looks weird.
Fix that bug in the transition by slightly extending the clip downwards
when animating between the window picker and the app grid state. The
extra height we extend the clip by is controlled by the overviewState,
which means we extend the clip by the full icon overlap in the window
picker state, but don't extend the clip at all when in the app grid
state.

We want to use as much space as possible for showing window previews in
the overview, and the title and close buttons of those windows are only
visible on hover, so we can show them above anything if we want.
On both primary monitors and secondary monitors, there's a certain free
space available towards the bottom edge of the monitor (on the primary
monitor we show the dash there, and secondary monitors just scale down
the Workspaces). We can make use of this by checking how much free space
there is available from the bottom edge of our allocation to the bottom
edge of the monitor, and then aligning the window previews to make full
use of this space.
So stop adding any padding to the edges of the Workspace, which will
make the windows a lot larger and completely fill the Workspaces
allocation.
The left, top and right monitor edges should always be far enough away
to accomodate the close button and hover scale-up of the window. Only
with the bottom edge of the monitor we have to be a bit more careful
(the overflowing height of the window title is quite big), so there we
check if enough free space is available. If there isn't enough free
space, we simply apply a bit of bottom padding again and shift the
window up.

The original parent of a dragged actor might have been destroyed after

`ThumbnailsBox` listens for the `showing` signal from the `Overview` to
create its thumbnails and destroys them on the `hide` signal. Since the
`showing` signal can be emitted multiple times when switching between
the shown and hidden state without ever fully completing the transition,
this will cause `_createThumbnails` to be called multiple times, each
time adding another set of workspaces.

When starting a gesture to open the overview while a transition to hide
the overview is running, Overview._shown will be first set to false when
starting the transition and then to true by the gesture before the
`onComplete` callback is called. The `onComplete` callback in this case
is `Overview._hideDone()` which starts a transition to show the overview
again which also emits the `showing` signal. Since the gesture emits a
`showing` signal as well, this results in two consecutive `showing`
signals without a `hiding` signal in between.
This breaks the `searchControler` which adds a key press handler to
start the search on `showing` and removes it on `hiding`. So every time
this happens a new handler that will never be removed is added,
resulting in the first key press being repeated.

For the primary monitor workspace thumbnail, we must keep the monitor
index in sync with what is currently the primary monitor index,
otherwise we might end up trying to move windows to non-existing
monitors.
For example, if the primary monitor index was 1 when the thumbnail box
was created, but later, the primary monitor index changed to 0, with the
other monitor being turned off, moving a window to one of the workspaces
on the workspace thumbnail, gnome-shell would attempt to move it to the
monitor with the index the primary monitor had in the past, with the
problem being that that monitor no longer exists.
Fix this by listening on the 'monitors-changed' signal on the layout
manager, and update the monitor index of the primary workspace
thumbnails box. Make sure to connect to the signal before creating the
thumbnails box, as the thumbnails box itself will listen to the signal
and recreate its actual thumbnails, and it must do this with the up to
date monitor index.

When OverviewControls goes from HIDDEN to APP_GRID, it constantly checks
if AppDisplay needs to be visible or not by checking the current overview
state is bigger than WINDOW_PICKER. Turns out in this case this check is
problematic, because when the current state trespasses WINDOW_PICKER, the
layout manager will have already positioned AppDisplay halfway to its final
position.
Use either the final or the current state, whichever is biggest, when updating
the AppDisplay visibility. It optionally allows passing the overview state
params to _updateAppDisplayVisibility() so that we avoid a few trampolines to

Window previews looks slightly offset to the left and top right now
because we don't use the same padding on all edges of the Workspace. We
do that because the oversize and overlap of the window previews is
different on all sides (for example the bottom overlap is very large
because there we show the window title).
To make sure window previews are always perfectly centered on the
Workspace, only use the largest one of the oversize values as spacing
and padding, and add the larger one of the overlap values for the
vertical padding in addition.
With this, we now center the window previews on the Workspace while
never overpainting the allocation of that Workspace to show overlays.

The logic that decides whether we should shift the window up when the
cursor rectangle overlaps with the keyboard rectangle doesn't work
properly right now, we want it to work like this:
- If the currently focused window is shifted up, keep it shifted up
until the cursor rect no longer overlaps the keyboard rect. To do that
comparison correctly, we need to adjust for the height the cursor rect
is shifted up by (keyboardHeight) and temporarily shift it down again.
- If the currently focused is not shifted up, we want to shift it up as
soon as the focus rect overlaps the keyboard rect. If that's not the
case, want still want to call _setFocusWindow(null) in order to shift
the previously focused window back down.
This fixes two issues: 1) We're currently shifting windows back down at
the wrong position of the cursor (that is y < keyboardHeight). 2) We're
not shifting down previously focused windows when focusing a different
window with the new focus in a specific region (y >= keyboardHeight &&
y + h < monitor.y + monitor.height - keyboardHeight).

So far the FocusTracker of the OSK can only recognize grab ops on a
window, that is when the user grabs the window using a mouse or the
touchscreen and actively drags it somewhere.
Window can also be moved using keyboard shortcuts, fullscreen buttons or
other ways which don't rely on grabs. Start also supporting those window
movements by listening to the "position-changed" signal on the currently
focused window and emitting the new "window-moved" signal in that case.
Because the OSK sometimes moves windows by itself, we temporarily
disconnect from that new signal while we move the focused window in
_windowSlideAnimationComplete().
This also takes care of resetting this._focusWindowStartY on movements
of the window.

Commit 8526776b4a changed the OSK to use
the translation-y property of the MetaWindowActor when animating a focus
window, which broke two things:
1) It's not compatible with the obscured region culling we do for
windows in mutter. That's because MetaCullable strictly operates in
integer coordinates and thus has to ignore any transformations
(translation-y is a transformation). Because of this, during the
animation and gesture, window damage is now tracked incorrectly,
introducing painting issues. The best fix for this would probably be
factoring in transformations when tracking damage in MetaCullable, but
that's not feasible right now.
2) It broke the shifting up of maximized and tiled windows, likely that
is because they are positioned using constraints internally, and mutter
enforces those constraints every time meta_window_move_frame() is
called, not allowing the window to move somewhere else.
To fix both issues, go back to the old way of shifting the window for
now, using the fixed y position of the ClutterActor. To make sure the
drag-up gesture still works, store the initial y1 position of the window
and then use that as a reference point for all our animations.

I suggested it myself when reviewing
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1668, so
here I am reverting that again...
The difference between calling _setFocusWindow(null) and simply
unsetting the focusWindow is that the former animates the window back to
its position before we shifted it up, while the latter simply "lets go
of the window".
In this case we actually want the latter because after the user grabbed
the window, we obviously should not animate it away right underneath the
users pointer/finger.

The focus rectangle of the OSK currently gets stored with an offset that
removes the global coordinates and makes it window-local coordinates.
This offsetting has been applied since the introduction of the
FocusTracker with commit fc5ab44704 and it
seems there's no real reason for it.
By removing this, we also emit position-changed when the window has
moved but the window-local coordinates stayed the same. We really want
to emit position-changed in that case because it might affect whether
the window needs to be shifted up.

Apparently some clients, including gtk don't "clip" the focus rectangle
to their window bounds when scrolling the focus outside the window. This
makes us shift up windows when the focus actually is no longer visible.
This issue needs fixing in GTK, it should probably stop reporting
focus changes when the focus moves outside of the visible view. We can
still do a little bit better on our side though and "clip" the rectangle
to the windows frame rect: If it moves out of the window, we simply stop
updating our focus rect.
The intersection check introduces a small problem though: Some clients
(for example gedit) will give us a cursor rect that has a 0 width or
height. This won't play well with graphene_rect_intersect()
(GrapheneRects never intersect if they are 0-sized), so we set the size
to 1 in case we get a 0-sized rectangle.

picked up.

move the window from the second monitor to another workspace like shown
in https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3547,
removeWindow() is called twice for it, presumably once for the second
monitor workspace, and then once for the first monitor workspace for
some reason. It is during that call that _windowSlots doesn't contain
the window, so instead the last element (index -1) is removed, leading
to the animation bug.

We block state updates while the indicator for the active workspace
is animating. To track that, we check whether the scroll-adjustment's
value matches the active workspace index. That works as long as the
adjustment's value changes after the active workspace, but not when
switching workspaces via SwipeTracker which only changes the active
workspace after transitioning to the new scroll value.
To fix that, update the indicator on workspace changes as well.

Animating items of the iconGrid involves calling a few more C functions,
which is quite slow. Especially calling ClutterActor.set_easing_delay()
is slow because we override that function in JS to adjust for the
animation slow-down factor. So add a small class variable to make sure
we only animate the icons of the grid when we actually need it.
This makes the average time spent in vfunc_allocate() of the iconGrid go
down to about 0.7 ms.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1713>
It's quite slow to access class variables in JS, especially when they're
backed by GObject properties. To avoid accessing them in every iteration
when we're looping through the children of iconGrid, store those values
to another variable and reuse that inside the loop.
This shaves off another 0.2 ms from iconGrids vfunc_allocate(), getting
the average time spent in that function down from 1.3 ms to 1.1 ms.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1713>
Using a preexisting array to iterate over is much faster than iterating
over the actors children using a "for ... of" loop, that's because the
latter calls into C functions to get the next actor all the time.
Also, stop using array deconstruction here, it turned out that this is
extremely expensive. When profiling this part of the code, it turned out
that only 9% of the time spent in _getChildrenMaxSize() is spent calling
the get_preferred_height/width() methods. When not using array
deconstruction, this time increased to 22%, still not great, but a lot
better.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1713>
We need to access the visible children of a page in inside
vfunc_allocate(), and since getting those children is quite slow (it
involves iterating over all the children of the actor) let's avoid that
and cache the array instead.
This reduces average time spent in vfunc_allocate() of the iconGrid from
1.6 ms down to 1.4 ms.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1713>
We call this._getChildrenMaxSize() from the allocate() vfunc of
IconGridLayout. Since the function is quite expensive, it slows the
layout process down a lot, so instead of re-calculating it on every
relayout, cache the max size of children.
This makes the average time spent in vfunc_allocate() of the iconGrid go
down from 2.3 ms to 1.6 ms.

Instead of always aligning window previews vertically at the bottom of
their row, only do that if we have multiple rows. If there's only a
single row of windows, align every window vertically centered.
This is a very small step towards the new layout for window previews in
the overview, but since the release of 40 is getting nearer and nearer,
changing more is not feasible anymore.

To ensure the workspace thumbnails are vertically closer to the window
picker than to the search, scale down the wallpapers by a fixed number
of pixels. Using 24 px for this means we'll take of 12 px at the top and
12 px at the bottom of the wallpaper, that's a better strategy than
always scaling it by a fixed factor since it doesn't change with the
monitor size.

The back → transparent transition gives it a very bad look when
booting and running the startup animation.
Use the same transition duration hack to ensure that the panel
starts completely transparent.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1678>
There's this little hack that we do to match the panel transition from
transparent to black with leaving the overview via swipe down. The only
problem is that, while the duration of the panel transition itself is
matches, the corners don't, and they get out of sync.
This isn't very noticeable with the swipe gesture, but it'll be much
more prominent when booting straight into the overview.
Bind the 'style' property of the panel to the corners', so that the
transition duration hack applies to all of them.

The new startup animation consists of rising the Dash from the bottom,
falling the search entry from the ceiling, and going from HIDDEN to
WINDOW_PICKER with an opacity applied.
One little trick from IconGridLayout was added to ControlsManagerLayout,
which is a promises-based wait for allocation. This is required to make
sure that the transformed position of the search entry is valid, which
is only the case right after an allocation.
This animation also ensures that the overview is shown right on startup.
For session modes that do not have an overview, continue using the same
fade + scale animation.

We want to avoid updating the input region on startup, since it incurs
in roundtrips to the X server, but not workspaces struts, since they
affect the visible clip of wallpapers in the workspace. Since next
commits will make the overview be the after-boot screen, we really
don't want the wallpaper to be clipped wrongly.
Allow updating regions while starting up, but only workspace struts.
Make sure input is not updated by accounting for 'this._startingUp'
on 'wantsInputRegion'.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1678>
This is an X11-specific routine, and building the list of input region rects
on Wayland is a waste, since it incurs in many trampolines only to throw them
in the trash.
Don't build input region rects on Wayland. By modifying the 'wantsInputRegion'
variable, it also skips actors that only update input, which is another small
optimization for Wayland.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1678>
LayoutManager doesn't update struts when there's any modal running. Turns
out, the Overview itself is a modal. That, and the fact that the Overview
will be the startup state, prevents the workarea to be updated.
Allow updating struts when there's no other modal than the Overview.

Let the goToPage call afterwards to take precedence, instead
of resetting the adjustment (thus the view) on the side.
This resulted in strange state when the last page contains
a single icon, and it is dragged. The last page being emptied
triggers a pages-changed signal, which half resets the view
to the first page while DnD is ongoing.
Letting goToPage do its business means we neatly clamp to the
closest page to currentPage, the last page in that case.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1630>
When clicking on the page hints, the hint rectangles being visible
in place and not moving together with the page is a bit too
distracting.
Since the page hints are not part of the iconGrid hierarchy and
we have just 2 general ones for prev/next page (i.e. no page
associated), do this sliding via some smoke and mirrors: We don't
slide the page hints, but a parent container for both of them, and
we also control opacity so that the container is fully transparent
mid-page. At the point it is transparent, the container can be
snapped to the other side of the page, and faded back in as it
slides together with it, so it always looks like it goes away and
comes from the right sides.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1630>
Depending on the available horizontal space, we may want to manipulate
the icon grid and scroll view spacing to result in an optimal layout
that has space left to preview prev/next pages.
The main change here is that, when adapting to the available size, the
space given to a page does not necessarily match the available space,
as we need to be able to show more than one page at a time.
With this decoupling of available and page sizes in place, we now know
how much space there is available in order to extend the padding between
pages, or the fade effect applied to the previewed pages.
Underneath, we rely a bit less on hardcoded CSS paddings, and a bit more
on the StScrollView::content-padding property.
All put together, gives us proper space management from ultra-wide
displays, to display ratios that are close to the optimal grid ratio.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1630>
When DnDing an icon, we show both previous/next page, and optionally
a "placeholder" actor to allow creating new pages. These sides on the
scrollview are drop targets themselves, allowing to drop an app onto
the next/prev page without further navigation.
Still, preserve the checks to maybe switch to prev/next page without
finishing the DnD operation, for finer grained operations.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1630>
Add the necessary animations to slide in the icons in the previous/next
pages, also needing to 1) drop the viewport clipping, and 2) extend scrollview
fade effects to let see the pages in the navigated direction(s).
The animation is driven via 2 adjustments, one for each side, so they
can animate independently.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1630>
We want to show left/right side pages during navigation, also in
FolderViews. Let this scrollview use the same style than the "all
apps" one, and generalize the name a bit.
This will compress the scrollview horizontally, so there's actual
overflow space to show these pages.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1630>
Instead of taking just vertical/horizontal offsets, take a ClutterMargin
to allow us set the fade offsets on each direction specifically. Also,
handle negative values in margins, the fade effect will run in the negative
space left by the scrollview padding instead. Another difference now is
that areas outside the extents of the effect will be transparent, instead
of the effect ending abruptly past the given extents.
This will be used by the app grid, in order to selectively let see either
of next/prev pages while navigating.
While at it, fix code style issues in st_scroll_view_update_fade_effect(),
and clean up unused variables from the GLSL code.

The workspace minimap is much less prominent than the old workspace
switcher, and serves primarily as an indicator.
That means that duplicating it on secondary monitors (if workspaces
on non-primaries are enabled) is harder to mistake for per-monitor
workspaces, so make some people happy by including the minimap on
every monitor.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
Now that the backgrounds was moved into workspaces, the fullscreen
views on secondary monitors are visually inconsistent with the
primary view, as there's no dash or search entry that reduces the
available height and allows adjacent workspaces to peek in.
Address this by adding padding above and below the view, so that
it is limited to 70% of the available height.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
Right now the handling of external monitors is relatively simple, and
consists of putting either an extra workspace or a full view on the
monitor, depending on the workspaces-only-on-primary setting.
We are about to tweak the behavior on secondary monitors, prepare for
that by splitting out an intermediate actor that manages the views on
non-primaries.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
At the moment views on non-primary monitors take up the entire work area,
so simply allocating the available size works. However we'll soon shrink
the views a bit to match the visuals on the primary monitor. As workspaces
keep the ratio, reducing their height will also reduce the width; override
the default allocate() to keep the extra workspace horizontally centered.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
At the moment, we only get the initial :should-show value when populating
the thumbnails. That only happens when entering the overview, so any
listeners to notify::should-show will perceive it as a change rather
than an initialization, which can result in unwanted transitions.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
We currently initialize the porthole to the screen size instead of
the monitor's work area we actually want. At the moment this doesn't
matter, as the minimap is created during initialization with the rest
of the overview, so we can expect a work area change that updates the
porthole to the correct values.
That won't be true for minimaps we put on secondary monitors, so make
sure we initialize the porthole to the actual values.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
The minimap is currently created once when populating the overview,
and kept around until the end of the session. That will change when
we start to also show it on secondary monitors, so do proper clean
up when destroyed.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
This is used to detect whether a click was short enough to select a
window and activate it or long enough to start a drag. Usually when
clicking on a window and selecting it, this leaves the overview, but
when clicking on a window on a neighboring workspace, the overview is
kept open, but selected is not unset in this case. So all attempts at
dragging the window after using it to switch workspaces will fail.

The property describes the target visibility (that is, the visibility
that will be set after the ongoing transition), and is therefore updated
at the start of the transition rather than from hideDone().
The overview gesture currently misses resetting it at the end, so it
is only updated to the correct state the next time the overview is
entered.

Since commit 9980c80619, the porthole position is ignored. As a result,
previews are only shown if the primary monitor is located at (0, 0).
To fix this, we either need to propagate the porthole to every thumbnail,
use a custom layout manager that applies an offset to all children, or
add an intermediate actor that offsets the contents.
The last option is the simplest and doesn't require calls into JS on
every allocation, so pick that one.

The preview was getting scaled up by a factor based on what is needed to
increase the width by activeExtraSize pixels. With windows that are
wider than than they are tall, this means that the size of the window
will not increase any more than activeExtraSize in any direction, but
for windows that are taller than they are wide, the vertical scaling
can exceed this. This would break some of the assumptions in the
reported size for the preview chrome and could for very narrow windows
result in a rather large scale.
To fix this, calculate the scaling factor based on whatever is larger,
the height or the width.

Since commit 0f1b566918, we use gjs' automatic getters/setters for

In the allocate() vfunc of WorkspaceLayout we use a small trick to make
the nonlinear animation paths when opening the overview less jarring:
Because a window might get smaller than its target size during the
animation, we make sure the size never drops below the final size
calculated by the layout strategy.
In the app grid the Workspace is very small though, and the size of a
window slot calculated by the layout strategy might actually be larger
than the workspaceBox. This means we might use the window slot size
instead of the workspaceBox size and end up with a window that's at the
correct position, but its size is too large.
Fix this by only applying this trick when we're animating towards or
from the state where we actually expect the workspaceBox to be larger
than the window slot, that is during the the transition from the session
to the window picker (or the other way round).

It should be allowed to set this._spacing to 0 and thus pass 0 as
rowSpacing or colSpacing to this._adjustSpacingAndPadding(). The current
if-condition there won't add the oversize to the spacing in case 0 is
passed though.
So change that if-condition and explicitely check for null instead.

Window previews can spill out of the container when their position in the
session overflows the monitor boundaries. In the past, Workspace didn't have
a visible background, and was (almost) always fullscreen, which would mask
this particular problem. However, nowadays, it is very much noticeable when
this situation happens.
Clip the window previews container to its allocation when the overview state
is bigger than WINDOW_PICKER. That is, between HIDDEN and WINDOW_PICKER states,
inclusive, no clipping is applied.

Instead of adding it to the window previews container, add it to Workspace
