Since last week , all my builds from the stable branch have this problem.
The text keep flickering when the mouse moves.

Qt was compiled with :
configure -prefix c:/QtSDK/Qt32-5.2 -opensource -confirm-license -debug-and-release -c+11 -no-icu -openssl -plugin-sql-mysql -no-dbus -platform win32-g+ -opengl desktop -nomake tests -nomake examples -nomake tests
