I'm not sure. I stay away from high quality mode. It seems to cause more problems than it solves, with me anyways.
It may have to do with your video card. What model is it? If it's a consumer card, ex Radeon or Geforce, you'll probably run into problems like these. The Radeon's, especially the newer ones, seem to work much better with OpenGL and Maya than the Geforces.
Imagination is more important than knowledge.
