*** Bug 346447 has been marked as a duplicate of this bug. *** *** Bug 350572 has been marked as a duplicate of this bug. *** *** Bug 350572 has been marked as a duplicate of this bug. *** > XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0" > after 45 requests (43 known processed) with 0 events remaining. This is bug #303450 again - the "new" qml stuff invokes the close directly again. Adding Xcb::sync(); to "Client::closeWindow()" doesn't help anything - QtQuick just sucks. The bug is still there in Kubuntu 15.10 and kwin 5.4.1: Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Application: kwin_x11 (5.3.0) Qt Version: 5.4.1 Operating System: Linux 4.0.0-040000-generic x86_64 Distribution: Ubuntu 15.04 -- Information about the crash: - What I was doing when the application crashed: I was running glxgears and was closing the window. $ glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 302 frames in 5.0 seconds = 60.256 FPS XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0" after 1380 requests (1380 known processed) with 0 events remaining.
