Jiminy cricket! Disabling hardware anti-aliasing does get rid of the flickering. Too bad that won't be an acceptable option for us. This has to be an OSG problem since it has gotten worse in OSG 1.2 compared to 1.0. Does anybody know if anti-aliasing setup changed somewhere?
The core OSG has little to do with the anti-aliasing options you've selected, it just renders to the graphics context you've set up.
From the profile of the problem It is unlikely that there is any
specific OSG related with this problem, the fact that it got worse with 1.2 is likely down to oddities in the driver, either a sensitivity in thread timing, or memory usage that just happens to cause problems. This isn't the first time we've seen problems with recent win32 NVidia drivers and OSG usage, the last one was related to non Producer based apps crashing with the Nvidia drivers, again this just so happen to not appear to be a problem under 1.0, but was a problem under 1.2, but pretty well everything that the OSG was sending to the OpenGL was identical. We found a workaround to the driver bug by explictly getting the extension string before any drawing occurred, this workaround can be found in the CVS version of src/osgUtil/SceneView.cpp. The bug has been reported to NVidia. Perhaps the problem you are seeing is related to the above, in which case you could try the CVS version of the OSG and see if it helps.
