Double negations are the spawn of the devil, and is_non_opaque() is
used like that to find out if it's opaque most often, change the
function name to see the glass half full.

The MetaBackgroundActor was ignoring the unobscured area altogether,
and just painted according to the clip area. Check the unobscured
area too, as it might well be covered by client windows.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/698
Wayland clients do this through the opaque region in the surface
actor. However X11 clients were considered fully transparent for
culling purposes, which may result in mutter painting other bits
of the background or other windows that will be painted over in
reality.

We want to clip it away if 1) The window is fully opaque or
2) If it's translucent but has a frame (as explained in the comment
above). The code didn't quite match and we were only applying it on
case #2.
Case #1 is far more common, and saves us from pushing some drawing
that we know will be covered in the end.

We first set the workspace to the transient-for parent's, and then
try to set on the current workspace. If both happen, we double the
work on adding/removing it from the workspace, and everything that
happens in result.
Should reduce some activity while typing on the Epiphany address
bar, as the animation results in a number of xdg_popup being created
and destroyed to handle the animation.

The default configuration of libinput-gestures utility invokes wmctrl to
switch between desktops. It uses wmctrl because this works on both Xorg
and Wayland (via XWayland). Unfortunately, this generates the following
warning message every time, in both Xorg and Wayland desktops:
"Received a NET_CURRENT_DESKTOP message from a broken (outdated) client
who sent a 0 timestamp"
The desktop switch still works fine. The tiny code change here removes
this specific warning because, as the prefacing code comment originally
said and still says, older clients can validly pass a 0 time value so
why complain about that?
I also refactored the "if (workspace)" code slightly to avoid the double
test of the workspace value.
This is submitted for MR
https://gitlab.gnome.org/GNOME/mutter/merge_requests/671.
On X11, mutter needs to keep a grab on the locate-pointer key to be able
to trigger the functionality time the corresponding key combo is
pressed.
However, doing so may have side effects on other X11 clients that would
want to have a grab on the same key.
Make sure we only actually grab the key combo for "locate-pointer" only
when the feature is actually enabled, so that having the locate pointer
feature turned off (the default) would not cause side effects on other
X11 clients that might want to use the same key for their own use.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/647
Some special modifiers (typically "Control_L" used for locate-pointer in
mutter/gnome-shell or "Super_L" for overlay) must be handled separately
from the rest of the key bindings.
Add a new flag `META_KEY_BINDING_NO_AUTO_GRAB` so we can tell when
dealing with that special keybinding which should not be grabbed
automatically like the rest of the keybindings, and skip those when
changing the grabs of all keybindings.

Glib stopped providing any fallback implementations on systems without
memmove() all the way back in 2013. Since then, the symbol is a simple
macro around memmove(); use that function directly now that glib added
a deprecation warning.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/689
Starting with commit 2db94e2e we try to focus a fallback default focus window
if no take-focus window candidate gets the input focus when we request it and
we limit the focus candidates to the current window's workspace.
However, if the window is unmanaging, the workspace might be unset, and we could
end up in deferencing a NULL pointer causing a crash.
So, in case the window's workspace is unset, just use the currently active
workspace for the display.
Closes https://gitlab.gnome.org/GNOME/mutter/issues/687https://gitlab.gnome.org/GNOME/mutter/merge_requests/688
Make it so it returns the closest ancestry MetaWindowActor if it
is a MetaSurfaceActor.
We need this for Wayland subsurfaces, so we can support actions like
Meta+Drag on them.

Saves us from using MetaCompositor API, at a point where it might not
be initialized yet. Use the same window directly, since we already
have it handy.

This is important when using a touchscreen or stylus instead of a mouse
or touchpad. If the cursor only gets hidden and the focus stays the
same, the window will still send hover events to the UI element under
the cursor causing unexpected distractions while interacting with the
touchscreen.
Fix this by emitting a visibility-changed signal from the cursor tracker
which then triggers a focus surface sync and always set the focus
surface to NULL when it's synced while the cursor is hidden.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/448
Allow checking whether the pointer is visible without accessing the
trackers internal is_showing property. While we don't need this just yet
for reading the visibility inside meta-wayland-pointer, it's useful when
implementing the logic to remove Clutter's focus when the cursor goes
hidden later.

COPY_MODE_PRIMARY has two paths, automatically chosen. For debugging purposes,
e.g. why is my DisplayLink screen slowing down the whole desktop, it will be
useful to know which copy path is taken. Debug prints are added to both when
the primary GPU copy succeeds the first time and when it fails the first time.
This is not the full truth, because theoretically the success/failure could
change every frame, but we don't want to spam the logs (even in debug mode)
every frame. In practise, it should be rare for the success or failure to ever
change. Hence, saying what happened on the first time is enough. This does
indicate if it ever changes even once, too, so we know if that unexpected thing
happens.
The debug prints are per secondary GPU since there could be several.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/615
When the preferred path META_SHARED_FRAMEBUFFER_COPY_MODE_SECONDARY_GPU cannot
be used, as is the case for e.g. DisplayLink devices which do not actually have
a GPU, try to use the primary GPU for the copying before falling back to
read-pixels which is a CPU copy.
When the primary GPU copy works, it should be a significant performance win
over the CPU copy by avoiding stalling libmutter for the duration.
This also renames META_SHARED_FRAMEBUFFER_COPY_MODE_* because the new names are
more accurate. While the secondary GPU copy is always a GPU copy, the primary
copy might be either a CPU or a GPU copy.

This bit of code was more or less duplicated in meta-renderer-native-gles3.c
and meta-wayland-dma-buf.c. Start consolidating the two implementations by
moving the *-gles3.c function into meta-egl.c and generalizing it so it could
also accommodate the meta-wayland-dma-buf.c usage.
The workaround in the *-gles3.c implementation is moved to the caller. It is
the caller's responsibility to check for the existence of the appropriate EGL
extensions.
Commit 6f59e4858e worked around the lack of
EGL_EXT_image_dma_buf_import_modifiers with the assumption that if the modifier
is linear, there is no need to pass it into EGL. The problem is that not
passing a modifier explicitly to EGL invokes implementation-defined behaviour,
so we should not have that workaround in meta-egl.c.
This patch intends to be pure refactoring, no behavioral changes. The one
change is the addition of g_assert to catch overwriting arbitrary memory.

Using the master device, as we did, won't yield the expected result when
looking up the device node (it comes NULL as this is a virtual device).
Use the slave device, as the g-s-d machinery essentially expects.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/678
The device ID is kind of pointless on Wayland, so it might be better to
stick to something that works for both backends. Passing the device here
allows the higher layers to pick.

As per commit f71151a5 we focus an input window if no take-focus-window accepts
it. This might lead to an infinite loop if there are various focusable but
non-input windows in the stack.
When the current focus window is unmanaging and we're trying to focus a
WM_TAKE_FOCUS window, we intent to give the focus to the first focusable input
window in the stack.
However, if an application (such as the Java ones) only uses non-input
WM_TAKE_FOCUS windows, are not requesting these ones to get the focus. This
might lead to a state where no window is focused, or a wrong one is.
So, instead of only focus the first eventually input window available, try to
request to all the take-focus windows that are in the stack between the
destroyed one and the first input one to acquire the input focus.
Use a queue to keep track of those windows, that is passed around stealing
ownership, while we protect for unmanaged queued windows.
Also, reduce the default timeout value, as the previous one might lead to an
excessive long wait.
Added metatests verifying these situations.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/660https://gitlab.gnome.org/GNOME/mutter/merge_requests/669
When used it setups an X11 event monitor that replies to WM_TAKE_FOCUS
ClientMessage's with a XSetInputFocus request.
It can only be used by x11 clients on windows that have WM_TAKE_FOCUS atom set
and that does not accept input.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/669
When using gtk under X11 some WM related events are always filtered and not
delivered when using the gdk Window filters.
So, add a new one with higher priority than the GTK events one so that we can
pick those events before than Gtk itself.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/669
As per commit f71151a5 we were ignoring WM_TAKE_FOCUS-only windows as focus
targets, however this might end-up in an infinite loop if there are multiple
non-input windows stacked.
So, accept any focusable window as fallback focus target even if it's a
take-focus one (that might not reply to the request).
Added a stacking test to verify this.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/660https://gitlab.gnome.org/GNOME/mutter/merge_requests/669
When looking for the best fallback focus window, we ignore it if it is in the
unmanaging state, but meta_stack_get_default_focus_window() does this is check
for us already.
So, ignore the redundant test.

Since 4cae9b5b11, and indirectly before that as well, the
MetaMonitorManager::power-save-mode-changed is emitted even
when the power save mode didn't actually change.
On Wayland, this causes a mode set and therefore a stuttering.
It became more proeminent with the transactional KMS code.
Only emit 'power-save-mode-changed' when the power save mode
actually changed.

We need to set XdndAware and XdndProxy on the stage window if running
