Description Ash 2022-04-03 07:06:38 UTC
SUMMARY
Touching the very edge of a touchscreen device can bring forward windows that are behind other, fullscreen windows, and are partially offscreen.

STEPS TO REPRODUCE
1. Open any application and move it so the window is partially offscreen.
2. Open a fullscreen-capable application (e.g. Firefox) and enter fullscreen (F11).
3. Touch the very edge of the screen, where your windowed application is overlapping it.

OBSERVED RESULT
The windowed application is focused.

EXPECTED RESULT
No applications switch focus and the fullscreen application responds to the touch.

Can reproduce. We're both on Wayland. This often happens for me when triggering an edge swipe.
Comment 3 Vlad Zahorodnii 2024-06-12 10:20:23 UTC
I seem to be unable to reproduce it. Is it reproducible with other scale factors? also can you check whether the issue is still reproducible in plasma 6?
