Public bug reported:
After locking my screen and coming back (<1 min), the external monitor
switched to 1080i instead of 1080p and all text gets blurry.
Reconnection of the display did not solve the issue. This has happened
on either 20.04 or 21.04 when I was using X.org. When using Wayland on
Ubuntu 21.10, this issue never appeared. Now it came back after Wayland
disappearing (#1968929).
