[Development] Spurious Flickering on Mac OS X Moutain Lion (Qt 4.8, OpenGL, QML 1.1)

we did have the same problem when using OpenGL as the drawing backend
for a QDeclarativeView based application on MacBook machines with 10.7
and 10.8.

As we didn't actually need OpenGL we could simply switch to raster
painter and so didn't bother about the problem any more.

Sorry I can't help you with a solution, but it seems you're not the
only one facing this problem.
