I can only assume it's a vsync problem, or perhaps something relating to the refresh rate of your video cards?
I've changed FLIP to VWAIT:FLIP FALSE and vice-versa a few times, so it must be related to that - I'm doing nothing odd with Blitz, just loading and displaying meshes, so I can only assume it's something specific to certain PCs rather than my program.
Do you get this problem with other Blitz programs? That corruption on the screen looks like graphics-card issue rather than something I could produce with what is effectively a very simple Blitz program (simple bar the physics routines - the rendering is bog-standard).
