Description jy6x2b32pie9 2025-07-05 15:15:57 UTC 
SUMMARY

When Grid or Overview shown on my two-monitor setup, it's shown only on one (left) display, with right display unaffected. When screenshotting, screenshot shows both screens having relevant view on them.

STEPS TO REPRODUCE
1. Connect two displays to DP.
2. Set right display as primary.
3. In System Settings, assign top left corner as "Grid", top edge as "Overview"
4. Activate one of those effects.
5. Press PrintScreen to get screenshot.
6. Exit grid/overview mode.

OBSERVED RESULT
Grid/Overview mode is visible only on left, non-primary monitors.
Screenshot captures Grid/Overview on both monitors.

EXPECTED RESULT
Either Grid/Overview visible and captured on both screens or screenshot agrees with visible image

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Gentoo linux
