Description Lukas Spies 2020-09-20 05:00:55 UTC

SUMMARY
When a window is set to 'Always on Top' then any of the popups of the panel (window previews, systray popups, application launcher) are shown *behind* that window instead of on top of it.


STEPS TO REPRODUCE
1. Set window to 'Always on Top'
2. Move window near panel
3. Hover over any window in the window list or open any popup.

OBSERVED RESULT
The popup is shown behind the window with the 'Always on Top' property set.

EXPECTED RESULT
The popup is shown on top of the window with the 'Always on Top' property set.

ADDITIONAL INFORMATION

I forgot to add: This is using Plasma with Wayland.

Comment 2 Lukas Spies 2020-10-02 14:51:05 UTC

I have a shortcut set to set a window to be shown always on top. I then noticed that if a panel popup opens behind an 'always on top' window I can use that shortcut to move it to the top.

Thus, it seems like all that is missing is to always set the 'always on top' window flag for the panel popups.

This bug is still freely roaming around!

This is specific to Wayland only. It doesn't occur on Xorg.
