I'm not really sure what's happening here, but I don't think these closed source games are good enough tests cases to diagnose the problem. Could you try to find a very simple Open Source mono program that will reproduce this bug?
It seems i'm able to reproduce the problem with opentk opengl examples: http://www.opentk.com/ http://sourceforge.net/projects/opentk/
