-Subject: [PATCH 67/68] Avoid calling potentially pure virtual method
-
-In Qt 5.4 screenChanged is called indirectly from the destructor of
-QPlatformScreen. By comparing new values against the oldScreen we call
-call virtual methods of QPlatformScreen from it's own destructor which
-results in a crash.
-
-This patch simply emits change signals whenever a screen change regardless
-of whether the value differs from the previous screen. Arguably less
-efficient, but better than crashing.
-
-This fix is not needed in Qt 5.5 where the QPA architecture has changed.
