Package: libqt5widgets5
Version: 5.3.2+dfsg-4+deb8u1
Severity: normal
Dear Maintainer,
Since a few days, QtWebKit applications (such as Calibre or my minimal
PyQt test script[1]) crash when resizing the window. I think it mostly
happens when it's resized bigger than the window size when the
application was started.
Sometimes there's a segfault, sometimes just a warning printed:
[...]
QXcbShmImage: shmget() failed (28) for size 103376 (364x71)
QXcbShmImage: shmget() failed (28) for size 905664 (636x356)
QXcbShmImage: shmget() failed (28) for size 921600 (640x360)
QXcbShmImage: shmget() failed (28) for size 8294400 (1920x1080)
QXcbShmImage: shmget() failed (28) for size 8294400 (1920x1080)
[...]
I also see drawing errors when using KeePassX (wich doesn't use
QtWebKit) with similar errors:
QNativeImage: Unable to attach to shared memory segment.
X Error: BadDrawable (invalid Pixmap or Window parameter) 9
Major opcode: 62 (X_CopyArea)
Resource id: 0x0

Everything non-Qt seems to work fine.
