ab3931fec8 backends/screen-cast-stream-src: Set correct stride when using dmabufs
Currently, mutter hardcodes the stride of all recorded images in a
screencast to width * 4.
While this stride is valid for general memory buffers, it is not
necessarily valid for dmabuf buffers, as the driver may need a specific
alignment of the stride.
This can currently result into import failures, e.g. when using the AMD
driver.

To fix this issue, retrieve the actual dmabuf stride, when using dmabuf
screencasts, and set it as the stride value in the PipeWire buffer.

f037c9df66 wayland/dma-buf: Don't require modifiers support for scanout tranche
When building the list of formats to be sent as part of the scanout
tranche, avoid requiring modifier support by the DRM driver for
formats relying on implicit modifiers (DRM_FORMAT_MOD_INVALID).

Specifically, the previous check required the DRM driver to have
advertised some modifier support for the given format in its
IN_FORMATS KMS plane property, regardless of modifier it was. If it
hadn't, the format was left out of the list of formats to be sent
in the scanout tranche.

When no formats remained to be sent in the scanout tranche, the
tranche simply wasn't sent.

This resulted in the scanout tranche never being sent for GPUs where
modifiers aren't supported. In those cases, no formats are advertised
using the IN_FORMATS property, and thus the list of formats to be sent
in the scanout tranche remained empty.

Since Mesa doesn't use scanout-compatible buffers for native Wayland
clients unless specifically requested to do so using the "scanout"
tranche flag, it effectively means that direct scanout of native
Wayland clients wasn't supported for GPUs without modifiers support.

Sending a tranche with formats paired with the implicit modifier
(DRM_FORMAT_MOD_INVALID) is both allowed by the protocol and is
already done by default for GPUs with modifiers support, unless the
experimental support for explicit modifiers is enabled in Mutter.

So instead of requiring modifiers to be supported for each format
being evaluated for the scanout tranche, when processing formats
which rely on implicit modifiers, only check if the format in
question is supported by the DRM driver for scanout on the primary
plane.

1a56a53909 wayland/actor-surface: Consider clones in is_on_logical_monitor()
While the check for `clutter_actor_has_mapped_clones` clearly indicates
an intention to take clones into account, the following code
does not do so, likely because it predates the introduction of
`clutter_actor_is_effectively_on_stage_view()`.

Switch to that newer API in order to take clones into account. This
avoids unnecessary `wl_surface_send_enter()` and `wl_surface_send_leave()`
events when entering the overview, reducing client work.

This also avoids unnecessarily allocating a `cairo_region_t`.

0f8f30c93f window-actor/wayland: Skip unnecessary set_child_at_index() calls
`clutter_actor_set_child_at_index()` is far from a no-op, even if
the current index is equal to the new one - presumably for good
reasons. For the use-case here we want it to be a no-op though, so
skip calling it if the index already matches.

57881ba612 wayland/subsurface: Move actor unparenting back to rebuild_surface_tree()
Unparenting the surface actor when the subsurface object is destroyed
has several issues:
 - subsurface actors can be unparented while a close animation is
   still ongoing, breaking the animation for e.g. Firefox.
 - adding and removing the actor to/from the parent is not handled in
   one place, making the code harder to follow.
 - if the destroyed subsurface had children of its own, they potentially
   stick around until a surface-tree rebuild. This makes the Firefox
   hamburger menu not close with the "compositor" backend.

Move the unparenting back to
`meta_window_actor_wayland_rebuild_surface_tree()` and instead just
notify the parent of a state change, if it still exist. This will ensure
a correct mapping between the subsurface node tree and the flat surface
actor list. In case of the closing animation the parent will already be
removed and the call is skipped.

640ca57c34 window: Close window when unsetting transient_for
Since b443bd42ac, we unmanage a wayland window when clearing its
transient parent. That's to make sure that xdg-foreign doesn't
leave the dialog around after the imported surface was destroyed.

While that behavior is sound, it is problematic to implement it
by unmanaging the window, as that happens entirely behind the
client's back.

Instead, send a close event for the window. Unless the client has
good reasons, it should honor the request. (And if it has good
reasons - like unsaved work - then effectively hiding the window
from both the user and client is probably not the best idea anyway).

7ff1c04c8f window: Guard minimize()
Not all windows can be minimized: X11 clients can disable the
functionality, and so do we for windows that aren't shown in
the alt-tab popup or the shell overview, so there would be no
way of getting them back.

While we make sure that we respect that ourselves (keybinding,
window menu, etc.), we don't guard meta_window_minimize(), so
clients or extensions can still minimize a window that isn't
supposed to be minimized.

That can lead to all kinds of issues, from the hidden window
being lost (as far as users are concerned) to a crash when
the minimzed window has a transient parent.

Just add an explicit check to make sure the unexpected doesn't
happen after all, and print a warning if it does.

9bdf4b3572 core/events: Fix cursor tracking for other backends
The cursor rendering code path used by the screen cast code relies on
the cursor tracker machinery to determine where to blit the cursor
texture, but at the moment the cursor position invalidation is behind
a check for whether the shell is using a Wayland backend. (This code
path used to be Wayland-specific before 00cbcb7ba1 but has been
backend-agnostic since).

This commit removes the check for a Wayland compositor, allowing
cursor drawing to function correctly on X11 when screen casting in
embedded cursor mode.

995ee2b638 tests/stage-view: Give outer container an explicit size
The test case checks that the stage views of hidden actors are
not updated when the views of the visible outer parent change.

The check for the outer parent's updated stage views currently
relies on ClutterFixedLayout not excluding hidden children in
its size request: As the container doesn't contain any visible
children at that point, its size would change to 0x0 and end
up on no stage view (rather than the assumed two).

Avoid that oddity by giving the outer container a fixed size,
so that the visibility of its child doesn't affect the test
when we fix ClutterFixedLayout.

003ff46a98 tests/xwayland: Wait for clipboard to settle before killing Xwayland
The test aims to test that trying to fetch X11 clipboard content after
Xwayland went away doesn't cause issues. What happens though is that
sometimes the clipboard content doesn't have time to settle (i.e. fetch
mime types etc) before Xwayland gets terminated, which causes flakyness.

Fix this by waiting for the compositor side clipboard owners to finish
setting up before continuing.

43860110ff output/kms: Replace common mode bandwidth check with clock check
The pixel clock determines how fast pixels can be processed. When adding
non-native common modes, avoid adding modes that exceed the max pixel
clock frequency of the native modes. Avoiding these avoids potential
mode setting failures where the GPU can't handle the modeline since the
configured pixel clock is too fast. This replaces the "bandwidth" check
which used the number of pixels and refresh rate, which wasn't enough to
avoid incompatible modes.

53b52e26f5 screen-cast/monitor: Always use clutter_stage_paint_to_framebuffer()
'screen-cast/monitor-src: Use clutter_stage_paint_to_buffer'
(6c818cd8d5) made the non-dma-buf path use
clutter_stage_paint_to_buffer() to avoid running into direct scanout
issues. At a glance, the dma-buf paths didn't have the same issue since
it explicitly handled dma-bufs by blitting them.

What it also did was move the recording to an idle callback, to avoid
paint reentry issues. A side effect of this, however, is that it also
broke the dma-buf paths, as they rely on the back buffer existing, and
the stage view direct scanout already being setup, which it isn't in an
idle callback.

Fix this by using the dma-buf variant of
clutter_stage_paint_to_buffer(): clutter_stage_paint_to_framebuffer().
This has some negative performance impact, but we can't use
cogl_blit_framebuffer() when using an idle callback for recording.

Potential performance improvements to make things work more as they did
before is to enhance 'cogl_blit_framebuffer()' a bit, making it a vfunc
that could be implemented by MetaOnscreenNative. A flag to say whether
to look at the back or front buffer would let MetaOnscreenNative know
whether to use the already committed-to-KMS buffer, or the current back
buffer.

it to TRUE. Lets remove the confusion that GLSL isn't supported and just
remove the (dead) fallback paths.

Ensure that buffer transforms are correctly rendered.

This test would fail without the commit
"wayland/surface: Swap 90 and 270 degree transforms"

11fc5b6c6c tests/wayland: Add more requests to test driver protocol
Add `sync_effects_completed()` and `verify_view()` in
order to allow Wayland test clients to trigger verifications
and add convenience functions to use them to client-utils.

Notes:
- `sync_effects_completed()` works in two stages in order
  to ensure it doesn't race with window effects. By the time
  `sync_effects_completed()` is processed, an effect could
  already have ended or not yet been scheduled. Thus we
  defer a check for pending effects to the next paint cycle,
  assuming that by then they should have been scheduled.
- `meta_ref_test_verify_view()` internally triggers the
  `paint` signal for the stage which is why it can not be run
  in the after-paint signal handler.

27dbf77d19 tests/wayland: Update documentation for MUTTER_REF_TEST_UPDATE
For some reason `LIBGL_ALWAYS_SOFTWARE=1` does not work as intended
while `MESA_LOADER_DRIVER_OVERRIDE=swrast` does.
