[Bug]: Ghost window at virtual desktop 1

[RollLikeRollo]

Summary

After upgrade from Fedora 38 to 39, KDE plasma, Wayland, Bismuth seems to think that there is an invisible window at the virtual desktop 1, while the task switcher does not show any windows. This behaviour occurs right after logging into the graphics target. This "ghost window" blocks clicking anything at the desktop, as well as the automatic krunner popup when I start to write anything with cursor at the desktop.

When opening any window, it covers only one half of the screen, and behave as if there were two windows. This happens in all layouts.

This occurs only at the desktop 1 and screen 1. All other desktops are fine for both screens I have. The desktop 1 is fine at the second screen.

I experienced the same too. For me, the Ghost Window is xwaylandvideobridge.

What I've done so far is to ignore the window

Settings > Window Management > Window Tiling > Window Rules

Under Ignore Windows, add an entry to your ghost window. In my case, it's xwaylandvideobridge

This is just what I was thinking. I try to avoid the videobridge if possible due to this exact issue, the thought never occurred to me to use a window rule lol I'll have to try that
