Both do more or less the same but with different methods - one puts
pixels into a buffer using the CPU, the other puts pixels into a buffer
using the GPU.
However, they are behaving slightly different, which they shouldn't.
Lets first address the misleading disconnect in naming, and later we'll
make them behave more similarly.

That was obviously always the intention, but it didn't work when the
display was scaled. My 3840x2160 monitor with a 3840x2160 texture was
being rendered with LINEAR filtering.
It seems the `force_bilinear` flag was TRUE when it should be FALSE.
Because a texture area that's an integer fraction of the texture
resolution is still a perfect match when that integer is the monitor
scale. We were also getting:
`meta_actor_painting_untransformed (fb, W, H, W, H, NULL, NULL) == FALSE`
when the display was scaled. Because the second W,H was not the real
sampling resolution. So with both of those issues fixed we now get
NEAREST filtering when the texture resolution matches the resolution it's
physically being rendered at.
Note: The background texture actually wasn't equal to the physical monitor
resolution prior to January 2020 (76240e24f7). So it wasn't possible to do
this before then. Since then however, the texture resolution is always
equal to the physical monitor resolution.

It doesn't take all children - subsurfaces in this case - into
account, thus creating glitches if subsurfaces extend outside
of the toplevel surface.
Further more it doesn't seem to serve any special purpose - it was
added in f7315c9a36, a pretty big commit, and no discussion was
started about the code in question. So it was likely just overlooked
in the review process.

gnome-shell displays workspace previews at one tenth scale. That's a
few binary orders of magnitude so even using a LINEAR filter was
resulting in visible jaggies. Now we apply mipmapping so they appear
smooth.
As an added bonus, the mipmaps used occupy roughly 1% the memory of
the original image (0.1 x 0.1 = 0.01) so they actually fit into GPU/CPU
caches now and rendering performance is improved. There's no need to
traverse the original texture which at 4K resolution occupies 33MB,
only a 331KB mipmap.
In my case this reduces the render time for the overview by ~10%.

The frame clock owner should be able to explicitly destroy (i.e. make
defunct) a frame clock, e.g. when a stage view is destructed. This is so
that other objects can keep reference to its without it being left
around even after stopped being usable.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
Currently there is a point in between hot plug, and when the stage view
list is up to date. The check also tests for this behaviour; would this
ever change, the test should be adapted to deal with this too.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
Replace the default master clock with multiple frame clocks, each
driving its own stage view. As each stage view represents one CRTC, this
means we draw each CRTC with its own designated frame clock,
disconnected from all the others.
For example this means we when using the native backend will never need
to wait for one monitor to vsync before painting another, so e.g. having
a 144 Hz monitor next to a 60 Hz monitor, things including both Wayland
and X11 applications and shell UI will be able to render at the
corresponding monitor refresh rate.
This also changes a warning about missed frames when sending
_NETWM_FRAME_TIMINGS messages to a debug log entry, as it's expected
that we'll start missing frames e.g. when a X11 window (via Xwayland) is
exclusively within a stage view that was not painted, while another one
was, still increasing the global frame clock.
Addititonally, this also requires the X11 window actor to schedule
timeouts for _NET_WM_FRAME_DRAWN/_NET_WM_FRAME_TIMINGS event emitting,
if the actor wasn't on any stage views, as now we'll only get the frame
callbacks on actors when they actually were painted, while in the past,
we'd invoke that vfunc when anything was painted.

This also changes the view construction path used by the renderer view
to use the new 'add_view()' function, meaning we have a common entry
point for views into the renderer, which will be useful later on.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
Before we'd create the view in init(), then continue poking at it in
realize(). Move all of the screen stage view initialization to
realize(), as that's when we have all the dependent state available.
This is possible since there is nothing needing it until realizing.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
The repaint callbacks are not tied to repaint, thus a bit misleading.
What the functionality in the pre/post-paint callbacks here cares about
is when actually painting; the non-painting related parts has already
moved out to a *-update signal.
This also renames the related MetaWindowActorClass vfuncs, to align with
naming convention of the signals that it listens to.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
Instead of going via MetaCompositor to know about when we updated
(confusingly named post-paint), use the new stage signal directly.
Note that this doesn't change the time frame callbacks are dispatched;
it's still not tied to actual painting even though it seemed so before
given the function names.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
The clutter "thread" repaint callback are not tied to painting, but
indirectly to updating. What the cursor renderer cares about is when we
actually painted, as this is related to the OpenGL fallback paths.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
We'd emit multiple "presented" signals per frame, one for "sync" and one
for "completion". Only the latter were ever used, and removing the
differentiation eases the avoidance of cogl onscreen framebuffer frame
callback details leaking into clutter.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
The vfunc was not tied to "paint", but was used by MetaWindowActorX11
as part of the "update" mechanisms. In order to make that more clear,
special case it in MetaWindowActorX11 by type checking the surface
actor, handling the case without MetaSurfacActor abstraction.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
The synchronization must happen no matter the painting, as it in itself
might result in reported damage, making the stage actually painted. Thus
move it out of the "pre-paint" handler, to something explicitly not tied
to the painting itself - ClutterStage::before-update.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
Instead of the 'pre-paint' signal on MetaCompositor, rely directly on
the 'before-update' signal on the stage. A reason for this is that the
callback should not only invoked in connection to painting, but updating
in general. Currently the 'pre-paint' signal is emitted no matter
whether there were any painting or not, but that's both misleading and
will go away.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
The mutexes was used by ClutterTexture's async upload and to match GDK's
mutexes on X11. GDK's X11 connection does not share anything with
Clutter's, we don't have the Gdk Clutter backend left, and we have
already removed ClutterTexture, so lets remove these mutexes as well.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
A frame clock dispatch doesn't necessarily result in a frame drawn,
meaning we'll end up in the idle state. However, it may be the case that
something still requires another frame, and will in that case have
requested one to be scheduled. In order to not dead lock, try to
reschedule directly if requested after dispatching, if we ended up in
the idle state.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
The native backend had a plain counter, and the X11 backend used the
CoglOnscreen of the screen; change it into a plain counter in
ClutterStageCogl. This also moves the global frame count setting to the
frame info constuctor.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
We currently have mutter set a global frame counter on the frame info in
the native backend, but in order to do this from clutter, change the
frame info construction from being implicitly done so when swapping
buffers to having the caller create the frame info and passing that to
the swap buffers call.
While this commit doesn't introduce any other changes than the API, the
intention is later to have the caller be able to pass it's own state
(e.g. the global frame count) along with the frame info.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
We had time unit conversion helpers (e.g. us2ms(), ns2us(), etc) in
multiple places. Clean that up by moving them all to a common file. That
file is clutter-private.h, as it's accessible by both from clutter/ and
src/.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
Currently unused, but it's intention is to use as a initial refresh rate
for a with the stage view associated frame clock. It defaults to 60 Hz
if nothing sets it, but the native backend sets it to the associated
CRTCs current mode's refresh rate.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
Without an associated actor, or explicit frame clock set, in the future
a timeline will not know how to progress, as there will be no singe
frame clock to assume is the main one. Thus, deprecate the construction
of timelines without either an actor or frame clock set.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
The MetaLater functionality needs to make sure an update is scheduled so
that it can run its callbacks etc. This used a ClutterTimeline (which is
an object more or less meant to drive animations markers, frames etc)
just to keep the master frame clock running. We're moving away from a
single master clock, so just schedule updates directly instead, with the
newly exposed API.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
We'd check if there was any queued redraw on the stage, but this is
inappropriate for two reasons:
1) A monitor and area screen cast source only cares about damage on a
subset of the stage.
2) The global pending-redraw is going away when paint scheduling will be
more view centric.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
The timestamp comes from the GSource, meaning it's a more accurate
representation of when the frame started to be dispatched compared to
getting the current time in any callback.
Currently unused.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
In certain scenarios, the frame clock needs to handle present feedback
long before the assumed presentation time happens. To avoid scheduling
the next frame to soon, avoid scheduling one if we were presented half a
frame interval within the last expected presentation time.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
This adds a current unused, apart from tests, frame clock. It just
reschedules given a refresh rate, based on presentation time feedback.
The aiming for it is to be used with a single frame listener (stage
views) that will notify when a frame is presented. It does not aim to
handle multiple frame listeners, instead, it's assumed that different
frame listeners will use their own frame clocks.
Also add a test that verifies that the basic functionality works.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
When a transition is created for the allocation change, it will delay
the new allocation box getting set depending on transition details.
This, however, means that e.g. the 'needs_allocation' flag never gets
cleared if a transition is created, causing other parts of the code to
get confused thinking it didn't pass through a layout step before paint.
Fix this by calling clutter_actor_allocate_internal() with the current
allocation box if a transition was created, so that we'll properly clear
'needs_allocation' flag.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1345
41130b08eb added a fix for culling subsurfaces with geometry scale.
Unfortunately it only did so for the opaque regions, not for clip and
unobscured regions, as the effect was hidden by bug that was only
fixed by 3187fe8ebc.
Apply the same fix to clip and unobscured regions and use the chance
to move most of the slightly hackish geometry scale related code
into a single place.
We need to scale slightly differently in the two cases, indicated by
the new `ScalePerspectiveType` enum, as the scale is dependent on the
perspective - once from outside, once from inside of the scaled actor.
Closes https://gitlab.gnome.org/GNOME/mutter/-/issues/1312
Since we now always return a resource scale, we can remove the boolean
return value from clutter_actor_get_resource_scale() and
_clutter_actor_get_real_resource_scale(), and instead simply return the
scale.
While at it, also remove the underscore from the
_clutter_actor_get_real_resource_scale() private API.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1276
Add private API to ClutterBackend to set a fallback resource scale
available to Clutter. This API will be used for "guessing" the
resource-scale of ClutterActors in case the actor is not attached to a
stage or not properly positioned yet.
We set this value from inside mutters MetaRenderer while creating new
stage-views for each logical monitor. This makes it possible to set the
fallback scale to the scale of the primary monitor, which is the monitor
where most ClutterActors are going to be positioned.

The portal API requires a screencast session only for absolution motion
with remote desktop, other methods including relative motion do not
require a screencast session.
There is no reason to be more strict than the API actually is, check for
a screencast session only when required, like for absolute motion events
and touch events.

There are a couple of places in gnome-shell where we aren't interested
in which workspace is active, but whether a given workspace is active.
Of course it's easy to use the former to determine the latter, but we
can offer a convenience property on the workspace itself almost for
free, so let's do that.

These tests were written (and copy-pasted) before ClutterActor
had an actual background-color property. As a preparation to
the removal of ClutterRectangle, replace all these rectangles
with plain actors and background colors.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1332
The property is deprecated and the current implementation simply
redirects it to ClutterActor::background-color, so remove it.
Also update the tests to set the background color directly.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1332
It is deprecated in favor of the 'z-position' property, and
the implementation itself redirects to the z-position, so
just drop it and replace all get|set_depth calls to their
z-position counterparts.

We were setting the pipeline colour to all white (1.0, 1.0, 1.0, 1.0)
and so the default layer combine function multiplied each pixel
(R, G, B, A) by all ones. Obviously multiplying by one four times per
pixel is a waste of effort so we remove the colour setting *and* set
the layer combine function to a trivial shader that will ignore whatever
the current pipeline colour is set to. So now we do **zero** multiplies
per pixel.
On an i7-7700 at UHD 3840x2160 this results in 5% faster render times
and 10% lower power usage (says intel_gpu_top). The benefit is probably
much higher for virtual machines though, as they're no longer being
asked to do CPU-based math on every pixel of a window.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1331
The previous commit removed checks for intermediate focus states which
would make tests randomly fail, because of their time dependence. What
can be tested however is that if there is no other window available that
would accept the focus, that the focus remains at 'none', after the
focused window has been closed. This newly introduced test checks the
focus directly after closing the window (and syncing) and after the time
it would have taken for the queue to finish. The first check has a
similar timing issue as the removed focus checks in the other tests, but
the test will never accidentally fail, because regardless of whether the
queue has finished or not, the focus is always expected to be 'none'.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1329
While c3d13203 ensured that the test-client has actually closed the
window before testing for the focus change, it also made another timing
related issue with the tests more likely to happen. Serveral tests
assert that the focus is set to 'none' after the focussed window has
been closed when the window below does not accept focus. This however
can never be reliably tested, because closing the window triggers
timeout based iteration of a queue of default focus candidate windows.
This starts after the window has been closed and might finish before the
clients have finished synchronizing. This issue is more likely to
trigger the shorter the queue is and the more test clients there are
that could delay the synchronization.

In commit 4c1fde9d MetaCullable related code was moved out of
MetaShapedTexture into MetaSurfaceActor. While generally desirable,
this removed drawing optimizations in MetaShapedTexture for partial
redraws. The common case for fully obscured actors was still supposed
to work, but it was now discovered that it actually did not.
This commit revert parts of 4c1fde9d: it reintroduces clipping
to MetaShapedTexture but leaves all culling and actor related logic
in MetaSurfaceActor.

When trying to find a default focus window, the code iterates through a
queue of candidates with a timeout between each candidate. If the window
the current timeout is waiting for gets destroyed, this process just
stops instead of trying the next window in the queue.
This issue was made more likely to be triggered with the previous change
to the closed-transient-no-input-parents-queued-default-focus-destroyed
test due to the introduction of a wait, which can introduce a
delay between the two destroy commands.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1325
Some tests were not waiting for the test client to actually issue
destroy commands before checking their effect on the window focus.
Similarly when mutter is supposed to change the focus based on a delay
by sending a WM_TAKE_FOCUS to the client, this also could fail without
synchronization with the client before checking the result.

We delegate the answer through CoglDriverVtable::is_hardware_accelerated

"hardware" making it so.

Event delivery with grabbing popups stay essentially the same within
the grabbing client, we still must honor the implicit grab as long as
there is one.
This is however not the case, the popup_grab_focus() function ignores
the button state. The popup_grab_button() function will already indirectly
re-sync the focus surface after the last button is released, so checking
for button state in popup_grab_focus() is sufficient to make the implicit
grab honored with popup grabs involved.

When a touch sequence was rejected, we'd update the event timestamps of
incoming touch events to help with implementing grabs. This was done by
sending a ClientMessage with a counter, and comparing the counter to
decide whether we're seing a replayed event or not.
This had the unforseen consequence that we would potentially end up
destroying all actors including the stage, since, when mutter receives a
ClientMessage event, it would assume that it's a WM_PROTOCOLS event, and
handle it as such. The problem with this approach is that it would
ignore fact that there might be other ClientMessage types sent to it,
for example the touch synchronization one. What could happen is that the
touch count value would match up with the value of the WM_DELETE_WINDOW
atom, clutter would treat this as WM_PROTOCOLS:WM_DELETE_WINDOW, which
it'd translate to clutter_actor_destroy(stage).
Destroying the stage in such a way is not expected, and caused wierd
crashes in different places depending on what was going on.
This commit make sure we only treat WM_PROTOCOLS client messages as
WM_PROTOCOLS client messages effectively avoiding the issue.
This fixes crashes such as:

Make the clutter_input_device_get_actor() API public and remove
clutter_input_device_get_pointer_actor() in favour of the new function.
This allows also getting the "pointer" actor for a given touch sequence,
not only for real pointer input devices like mice.

Add a method to ClutterSeat that allows peeking the list of input
devices and allow looping through devices a bit faster. The API left is
private so we can make use of peeking the GList internally, but don't
have to expose any details to the outside, which means we'd have to
eventually stick with a GList forever to avoid breaking API.
Since we now have the peek_devices() API internally, we can implement
ClutterSeats public list_devices() API using g_list_copy() on the list
returned by peek_devices().

As explained in the last commits, we'll let gnome-shell take care of
this since freezing and thawing needs to be decoupled from the effect
starting and ending.
So stop freezing the MetaWindowActor when starting the effect and
thawing the actor when ending the effect.

As explained in the last commit, gnome-shell needs to be able to thaw
window actor updates during its size-change effect is active.
So make meta_window_actor_freeze() and meta_window_actor_thaw() public
API, which will allow the shell to freeze and thaw actor updates itself.

The size-change animation in gnome-shell needs to sync the window actors
geometry during the animation, it currently does this by notifying the
compositor that the animation was finished before it actually is.
This causes a few bugs in Mutter though, since it will now emit the
"effects-completed" signal on the window actor even though they aren't
completed.
To fix that, we need to decouple freezing and thawing of actor updates
from window effects and allow gnome-shell to thaw actor updates before
it notifies Mutter that the effect is completed.
The first step for this is allowing to sync the actor geometry while an
effect is active, this should be redundant since effects which actually
need to inhibit those updates will freeze the actor anyway. Also a
geometry change happening while another effect is active will kill the
old effect anyway because MetaPluginManager kills all the active window
effects before starting a new one; so the new size-change effect for any
geometry change is going to kill the current effect.
