Created attachment 113924 [details] plasma_black_margin Sometimes, right after plasma startup, an area of roughly three-fourths of the desktop is in black, and the desktop is shifted to the right. This is fixed with a plasma restart. Attached is a screenshot of this problem in action. I'm not sure what produces the bug but happens sometimes at startup.
Pls issue qdbus org.kde.KWin /KWin supportInformation and paste output here. Also gather plasma startup log from $HOME/.local/share/sddm/

This is the output I for from qdbus in an initialization in which this problem happened: KWin Support Information: The following information should be used when requesting support on e.g. http://forum.kde.org. It provides information about the currently running instance, which options are used, what OpenGL driver and which effects are running.

Haven't experienced the bug anymore in recent plasma versions. OTOH I'm using different hardware now (AMD) than when this bug used to happen (intel).
Thanks for the update David. I'm going to mark this as resolved for now. If you swap hardware again in the future and the issue is present please reopen this report.
