--- Comment #1 from Martin Flöser <mgraess...@kde.org> --- >From the backtraces it looks like a problem in xlib. In both cases we do an xlib call which then triggers an error which goes back into xlib. I can understand how that can end up deadlocking in xlib. In both cases the triggering code is not in KWin, once it's KWindowsystem, once it's Qt. KWin itself is mostly Xlib free, but of course OpenGL requires Xlib. The issue might be arm specific. My suggestion is to give Wayland a try, it should perform better on arm and won't be able to trigger this issue. -- You are receiving this mail because: You are watching all bug changes.
