Description Akseli Lahtinen 2024-01-15 15:16:31 UTC
SUMMARY

Very edgecase bug, but some screens have a picture-by-picture setting. When turning it on, screens sometimes have 
a gap between them, but display manager warns about this.

When setting picture-by-picture off, the screens can overlap each other, causing some weird issues.


STEPS TO REPRODUCE
1. Enable PBP mode in a supported monitor
2. Open display settings, check that both outputs are enabled
3. Move outputs next to each other if they're not (settings will warn about this)
4. Apply
5. Now turn off the PBP mode
6. Display settings show both outputs on top of each other


OBSERVED RESULT
Displays start acting weirdly

EXPECTED RESULT
Display settings would not allow this setting to be valid and user would have to either
move the displays themselves or they're moved automatically.
