    Description

      Hi,

      We encounter a crash when one of our application closes.

      Reason for that is a WM_DISPLAYCHANGE message being handled, leading to the qDisplayChangeObserverWndProc() being called. This callback calls the following code:

      QWindowsContext::instance()->screenManager().handleScreenChanges();

      However, at the point it's called, QWindowsContext::instance() has been set to null, and that call crashes.

      Below a screenshot of the callstack:
