I had another Blitz user test my game recently, and we found that the latest version of Blitzmax runs just fine in windowerd mode on his system, but neither the DX or OpenGL drivers run properly when in fullscreen. The screen is redrawn more slowly than usual. He is apparently running his system at 120hz refresh in 800x600, but this has not been an issue before.
It just occured to me that since the last version I removed the flip fix for buffered directX drawing, but I did that because Mark said that he got rid of buffered DirectX support. So that fix should no longer be needed. I guess I will have him try it with the flip fix back in place and see if that corrects the issue.
On the other hand... That issue wouldn't also affect OpenGL. So it must be something else causing this in the latest version.
