- Does it happen if using another widget style ? (like Plastique or Cleanlooks) Regards Looks like Qt does not check the result of qt_toX11Pixmap (qpaintengine_x11.cpp:1908), it simply accesses X11 pixmap data later. @Christoph: could this be reported to Qt ? Bug 232800 and bug 233293 seem related to this too. *** Bug 228811 has been marked as a duplicate of this bug. *** From bug 229814: -- Information about the crash: I opened the systemsettings window, and tried the move to the sides to get the window maximized to the whole, or just a part of the screen. First I tried to the left side, which worked, next I tried to the top, when it crashed. From bug 228811: -- Information about the crash: I got this crash when I copied (ctrl-c) a large email (6.2 MB) in KMail to the clipboard and then opened the Klipper menu in the system tray. It doesn't seem related to KMail though, if I open a large text file in emacs, copy the text and then open the Klipper menu the same crash happens. The crash can be reproduced every time. *** Bug 229814 has been marked as a duplicate of this bug. *** *** Bug 216280 has been marked as a duplicate of this bug. *** *** Bug 227536 has been marked as a duplicate of this bug. *** Bug 234568 mentions some errors in the shell output (QPainter related) *** Bug 234568 has been marked as a duplicate of this bug. *** i got systemsettings to crash with the plastique style:

I had the same thing but rather than resizing the application (konsole) directly I had dragged it up to the top of the screen so kwin would resize to the entire screen.

The issue seems to be in video drivers failing to allocate memory to convert images to pixmaps (and Qt failing to handle that case). To help identifying the bug, please state (if possible) - xorg version - type of graphics/video drivers and version For the crash in Qt, I filed http://bugreports.qt.nokia.com/browse/QTBUG-12826 Still we need more information, why and where pixmap allocation could fail. It may be caused by pixmap leakage in other components or fragmentation in video card memory (anyone remember the "black windows" bug?) Created attachment 50007 [details]
