Description jdl 2023-04-21 10:35:54 UTC

SUMMARY
Bright part / background element behind panel (especially top panel) de-floats before the panel itself. This produces a jarring effect.


STEPS TO REPRODUCE
1. Activate floating panel on top panel
2. open a window on one virtual desktop
3. switch between virtual desktops

OBSERVED RESULT
A bright "halo" around the outer parts of the top panel becomes visible, de-floating slightly ahead of the normally visible part of the panel.

EXPECTED RESULT
Visible parts and non-visible parts of the panel float and de-float in lock-step, providing a uniform and consistent appearance.

Can confirm.

Can't reproduce anymore in current git master, which will become Plasma 6.2 soon. Assuming it was fixed by the great floating panel refactor of 2024. :)
