Bug Description
Graphics were working perfectly until update to 21.10.
Now I experience graphics lag when typing and moving the pointer, and clipping when scrolling or playing video.

Thanks for the bug report.
First please try disabling all extensions in the Extensions app, then log in again.
If the bug still occurs then next edit /etc/default/grub and change:
GRUB_ CMDLINE_ LINUX_DEFAULT= "quiet splash"
to:
GRUB_ CMDLINE_ LINUX_DEFAULT= "quiet splash i915.enable_psr=0"
and then run:
sudo update-grub
and reboot.
If the bug still occurs after that then while it is happening please run:
journalctl -b0 > journal.txt
and attach the resulting text file here.
