Description
Behaviour described in QTBUG-18852 reappeared again when building QT application in Microsoft Visual Studio 2012. Using QTimer for animating QGlWidget with intervals < 20 causes window lockups on window move, and total application freeze when right mouse button is invoked on window title bar. More lower QTimer interval is, more severe behaviour is. Same code build in MSVS10 works fine. Testing revealed, problems arise even when QTimer is not connected to animating slot, simple starting it with low interval causes mess with windows.
