I can confirm that I use a QGLWidget with Qt 4.6 binary build Cocoa on Mac OS 10.6.2 without problems :) I know, that is little help to your problem, but it might make the "future" a bit brighter ;) (and be a strong hint that the problem really seems to be in the GL driver shipped with Mac OS 10.5 or wherever, assuming that you are also using the latest Qt 4.6.x).

The stuff which is drawn is admittedly very simple: 2 triangles with a texture on it, using Qt shader programs (so basically I draw a "photo" ;)

Cheers, Oliver
