ApplicationWindow / QQuickWindow applications hang on exit with AMD fglrx driver

  • I'm having problems properly closing my application, because after closing its main window, the process keeps running in the background.

    After minimizing the code samples I've got to find that not even the default app template offered by Qt Creator is working. I'm referring to the "New Qt Quick Application" offered by Qt Creator.

    It seems to be exactly what it's explained in this closed bug report:

    I also got a stack trace mentioning the library; I got it as explained here: (as the application closes perfectly fine while debugging, so I can't get a stack trace in Qt Creator)

    0x7f557890fff0 : /lib/x86_64-linux-gnu/ [0x7f557890fff0]
    0x7f5576176b00 : /usr/lib/fglrx/ [0x7f5576176b00]
    0x7f557890fff0 : /lib/x86_64-linux-gnu/ [0x7f557890fff0]
    0x7f5576176c6f : /usr/lib/fglrx/ [0x7f5576176c6f]
    0x7f5576176f3f : /usr/lib/fglrx/ [0x7f5576176f3f]
    0x7f557614cb11 : /usr/lib/fglrx/ [0x7f557614cb11]
    0x7f5576141002 : /usr/lib/fglrx/ [0x7f5576141002]

    So I guess maybe this bug should be reopened?
