Public bug reported:
I recently upgraded my system from Ubuntu 18.04 to 22.04 and I started
having issues with my video.
If I use the kernel 6.5, my resolution will drop to sub-optimal (it
should be 1920x1200). Using the 6.2 kernel will allow me to choose
optimal resolution, but the CPU usage blows up for gnome-shell by simply
moving the cursor (usage > 50% according to "top" command).
Below is the info from my system.
