Major instability in Wayland when changing display scaling
Affected version
- Fedora 36
- GNOME 42.1
- Wayland
- AMD GPU (RX 5700 XT) on open source drivers
Bug summary
I have a 4K display. In Wayland, I changed the scaling to 300% as that feels comfortable in my setup. Upon changing this scaling, every single app I open crashes. Any app, be it a Gnome app like Settings, or something else like Gimp. Even worse, if you have your user set to auto login, the bug will persist after reboots. You will need to log out and sign back in under wayland for it to work properly again. Oddly enough, everything else works fine while in this state. Activities, menu panels, compositing, app drawer all function, but any open app or newly opened app will crash instantly. After logging out and in, it will work correctly without issue.
Steps to reproduce
- Use a high DPI display capable of 300% scaling (like 4K) (may happen on fractional scaling but untested)
- Set scaling to 300% on Wayland
- Cry as all open applications and newly opened applications completely crash :(
What happened
Crash any running apps
What did you expect to happen
Simply set display scaling
Additional notes
Setting resolution from 4K to 1080p did not have any unexpected behaviour.
