That's why I thought this is the right place ... Game developers or in this special case: Game Engine developers like BRL ... we have not much influence ... it seems to be a Blitz DX7 issue.
All other development tools that were updated or switched to DX9 do not show that problem (Pure Basic, Dark Basic Pro).
It appears only in fullscreen mode and the second GPU reacts on the mouse position .. hard to decribe ... and screenshots are not possible because they show no error.
The screen is updated while flipped till the vertical mouse position. Mouse at the bottom ... full screen is updated ... mouse somewhere in the middle then flip works only till that position ... the rest is written over and over.
I would blame it on the way Blitz handles the double buffering ... other development systems do not have the problem... so the first try should be ... work on Blitz ... if this does not help then look for other possibilities...
After 5 month when I reported this the first time, there could have been done something, if BRL would care about their flagship (quote Blitzbasic homepage: Our flagship product is Blitz3D,...) instead of letting it get rusty
