Bug Description
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.

The high CPU looks like it's just because the system is using software rendering, because there's no GPU. Ideally moving a mouse cursor shouldn't need a real GPU though, just basic display hardware.
While the high CPU is happening, please run:
sudo apt install drm-info
sudo drm_info > drminfo.txt
journalctl -b0 > journal.txt
and attach the resulting text files here.
