Description Henning 2023-08-08 21:25:38 UTC

KDE Wayland session:

I have multiple programs open with their individual surfaces. I open a menu so a subsurface in one program, in this case "Ardour Flatpak". In the task switcher I move to program "Elisa Flatpak" or anything else.

What happens?
The subsurface (menu) stays open, although the main surface (application) is hidden, as the main surface of another app is positioned above it.

What should happen?
Subsurfaces of apps (surfaces) that are covered by other main surfaces should always collapse in that case. Currently sometimes they stay open, and are on top of the main surface of the program covering their parent surface, which makes no sense.

Specified App:
kf5-kwindowsystem-5.108.0-1.fc38.x86_64
kwin-libs-5.27.6-1.fc38.x86_64

Can you provide a screenshot showing the problem? I'm confused by you mentioning subsurfaces

Comment 2 Nate Graham 2023-08-09 19:18:02 UTC

I think by "subsurface" he means a context menu that opens as a separate QWindow.

Cannot reproduce in Plasma 6.

Comment 3 Henning 2023-08-26 01:55:21 UTC

Yes I guess thats it.

Main window of for example firefox, I right click somewhere and there pops up a menu as a seperate wayland something.

When I have the main firefox window in the brackground though, the menu may still be in front, even though for example libreoffice is now in the foreground.

I havent seen this bug in quite a while, it was there a lot, may have been fixed.

Wait, you are using Plasma 6?

Yes, I'm using Plasma 6.
