--- Comment #3 from tamius....@gmail.com --- Created attachment 98595 --> https://bugs.kde.org/attachment.cgi?id=98595&action=edit xprop -spy > log I apologize for not following up sooner, since this bug was seemingly fixed for a while. It still happens though (in 5.6.3), but it seems to be mostly caused by disabling/re-enabling kwin_x11. Mouse is nowhere near the edge, but the panel will become visible and won't hide until I move the mouse over. It doesn't matter if the app is fullscreen or windowed. It only popped up recently since kwin now apparently allows some programs to disable compositing. In attachment, there's the output of xprop -spy. I've annotated where panel gets visible — that's lines which start with a few ####. -- You are receiving this mail because: You are watching all bug changes.
