a JPEG file onto GIMP's splash screen
- Fix a crash in X11 input device handling

Title:
Gnome resizes framebuffer when playing fullscreen video over and over
again (when using X11 fractional scaling)
Status in mutter package in Ubuntu:
Fix Released
Bug description:
When I play a video with mpv (or e.g. Firefox), it works just fine.
When this video is fullscreened (e.g. in mpv by pressing f), the
screen quickly turns off, and switches resolution modes in such a rate
the screen is unusable.
The native resolution of the screen is 1440p, but Xorg somehow
increases the size to 3424x1926 for the fullscreen, then quickly
switches back to 1440p, before increasing it again.
As soon as the video is de-fullscreened (by pressing f again in mpv,
or esc in Firefox), the funny resolution switching stops and the
system is usable again.
This also happens with the modesetting 2d-driver. This does not happen
with Wayland.
This can be seen in the Xorg-log:

When the resolution is increased, the Kernel complains about the
framebuffer size:
[ 269.830034] [drm] Reducing the compressed framebuffer size. This
may lead to less power savings than a non-reduced-size. Try to
increase stolen memory size if available in BIOS.
