Bug summary
External monitor connected to Nvidia dGPU freezes shortly after start
Steps to reproduce
- Log in into Gnome wayland session
- After login click anywhere to exit overview
- External monitor no longer updating
What happened
External monitor connected to Nvidia dGPU keeps updating only if there is something to draw (e.g. moving windows around, entering/exiting overview). Once there is a small pause in updates - it stops refreshing and shows last frame only. At the same time primary laptop display connected to iGPU continue to work fine without any issues.
This is a regression after !2777 (merged). Works fine on 44.3 and main branch up to "KMS Thread" merge.
What did you expect to happen
External monitor working fine
Relevant logs, screenshots, screencasts etc.
