--- Comment #6 from madc...@atlas.cz --- Unfortunately the root cause is probably even more elusive than I had originally thought. One window got moved to (0, 0) position without any change in display configuration. The window was on a virtual desktop that I was not using when it happened so I don't know what exactly triggered it. I know I was moving some windows around to arrange them neatly for some screenshots. Additionally, when this happens, KWin seems to become confused about the display setup. This manifests by new windows opening on the wrong screen or the window snapping feature using wrong dimensions. I'm afraid that there is no easily discernible way how to trigger this but it keeps happening rather frequently -- You are receiving this mail because: You are watching all bug changes.
