I run Ubuntu 22.04 on a Dell Optiplex 7010.
This issue started suddenly a couple of weeks back - I run updates several times weekly so not exactly sure when it started.
Just tried adding
 MUTTER_DEBUG_FORCE_KMS_MODE=simple
to environment file and after reboot, problem seems to have been resolved.
Thank you !
