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.
