I talked to Maarten on IRC about this. The problem seems to be that his 
monitor takes ages to mode switch, but ChangeDisplaySettings returns before 
this modeswitch is done. Also the opengl driver attempts to draw before the 
setup is ready, which fails and causes the test failures.

So it sounds like a driver bug which will only affect the tests(since games 
draw repeatedly and do not care if the first few frames do not render 
properly)
