For completeness' sake, also specifiy in the PIXELFORMATDESCRIPTOR to use no
depth, stencil and accum bits to initializing WGL when we can't (yet) use
wglChoosePixelFormatARB(), as we must always fist have a base legacy WGL
context using ChoosePixelFormat() before we can use that to use
wglChoosePixelFormatARB(), or if wglChoosePixelFormatARB() is somehow not
available for us.
Some drivers, however, enforces enabling depth buffers, so if we can't
acquire a pixel format that disables depth buffers, retry acquiring one
with that, which sadly is not optimal but we must make do.
Attempts to complete fix for issue #6401.
GdkVulkanContext is deprecated and only exposed in the api because
we need it as return type of the (deprecated)
gdk_surface_create_vulkan_context() API.
In fetch_net_wm_check_window(), before updating the wmspec_check_window, a
check is performed to verify a 15s difference between last_wmspec_check_time
and the current monotonic time.
The comment suggests that this check is done to ensure that it doesn't check
for a new check window repeatedly over and over again. While that was the case
origionally, currently the last_wmspec_check_time only gets updated when
wmspec_check_window is set, which is already checked earlier, making the time
check useless.
This check causes issues on cold boots where gtk4 applications are not able
to obtain the wmspec_check_window until 15 seconds after boot, making gtk
unable to check for extended wm_hints during that time.
Fixes: #6558
Do the backend call before changing the stacking order in the
frontend. This is necessary so the backend can look at the current
stacking order to determine if it will change.
Only commit things that have changed. In the ideal scenario, only
the texture changes from frame to frame, and all the sizing related
setup and the background stay the same, causing the least amount
of work in the compositor.
Rename things so they make more sense. The dest/source naming got
a bit unclear when we added background into the mix. Now we're going
for:
source_rect - the texture region to display
texture_rect - dimensions of the subsurface showing the texture
background_rect - dimensions of the background subsurface
bounds - union of texture_rect and background_rect
Also use this opportunity to add some api docs.
Make it possible for subsurfaces to have a black background on a
secondary subsurface below the actual subsurface. Using a single-pixel
buffer for that background increases the changes that the compositor
will use direct scanout for the actual subsurface.
This changes the private subsurface API. All callers have been
updated to pass an empty background rect.
This is useful for debugging offloading without having to rely
on gstreamer giving us dmabufs. To use it, set
GDK_DEBUG=force-offload
in the environment.
If there somehow end up being no `supported_versions`, `ctx` would end
up being dereferenced before being initialised. While I think that’s
unlikely, the compiler doesn’t know that, so let’s just initialise the
variable unconditionally.

This drops cursor and eraser source names to account for their removal
from GdkInputSource so that GDK_DEBUG=input debug message correctly
prints source type in X11 environment.

Allow to specify a D₂ transform when attaching a texture to a
subsurface, to handle flipped and rotated content. The Wayland
implementation handles these transforms by setting a buffer
transform on the subsurface.
All callers have been updated to pass GDK_TEXTURE_TRANSFORM_NORMAL.
This should give us more flexibility for buffer size vs surface
size.
Unfortunately, mutter doesn't play along currently, so this is
only useful for kwin, weston or sway.
Add a variant of GdkCursor that obtains the texture for the cursor
via a callback. The callback gives us the flexibility to handle
fractional scales and update the cursor for cursor theme size
changes as well as scale changes.
