That line is apparently: XRenderPictFormat *pictFormat = XRenderFindVisualFormat(display, visual->visual); which presumably means "visual" is NULL. "visual" is: XVisualInfo *visual = glXGetVisualFromFBConfig(display, chosenConfig); which "Returns NULL if config is not a valid GLXFBConfig." but chosenConfig is "configs[i]" which is returned from glXChooseFBConfig, so as far as I can see the only way it can plausibly be invalid is if your OpenGL stuff is broken for some reason? Qt could actually check for a NULL return and do "chosenConfig=NULL; continue;" though I guess. > #13 0x00007ffff6ef1477 in QSystemTrayIcon::setVisible (this=<optimized out>, > visible=<optimized out>) > at util/qsystemtrayicon.cpp:271 Maybe /usr/lib/x86_64-linux-gnu/qt5/examples/widgets/desktop/systray/systray might reproduce the crash?
