Description
Easiest to reproduce with a dual monitor Xinerama setup with one 4K monitor: Using any widget-based application, try to resize the window to cover both screens.
It crashes after a warning of the type "QXcbShmImage: shmget() failed (22) for size 35101960 (4159x2110)".
The problem is that we are trying to allocate a backingstore that is bigger than the maximum shared memory size on Linux.
