uncorrupted desktop

To give you a better idea of the corruption, here is a screenshot of the
desktop in normal circumstances.

This is running the new GNOME based Ubuntu GUI with Gnome-Shell Wayland, right?

With "Windows control did not work" you mean it doesn't respond to
mouse-clicks?

In that case it is known bugs/limitations in gnome-shell for depth 30/10bpc
mode. GNOME Shells picking code can't handle 10 bit per color channel.

Additionally Gnome-Shells Wayland compositor doesn't handle anything but
bgrx8888 or bgra8888 framebuffers in its drm/kms backend. It takes whatever
framebuffer format it gets, e.g., bgrx1010102 and hands it to the kernel as
bgrx8888, so the gpu misinterprets a 10 bit image as a 8 bit image during
scanout, which ends badly.

Right, so this is NOTOURBUG. Zebulon, your issue should disappear when you do
apt-get update again since allow_rgb10_configs defaults to 'false'.

Mario, do you know if there us existing Gnome bug about this? (did not find
such) Maybe easiest workaround for them would be to ignore 10bpc until picking
and kms backend is fixed.

I can't help you anymore. I removed oibaf repo and switch back to original
ubuntu driver.
