Application crashes after calling show() function of QGraphicsView on Mac OS
After porting from QT 4.8 to QT 5.2 a desctop application crashes when opening QGraphicsView for the second time using show() function, whereas the first time it works properly. There is an error message "Invalid drawable".
The error is deteced on Mac OS, on Windows OS the function works properly.
How can I resolve the issue?
Thanks in advance.
