I think this may be a video card/driver issue.
I've been doing a lot of moving windows around the screen and sometimes a line is left behind, minimising and restoring the window clears it.
I had a similar problem with CadStd (a CAD package) where the flash screen wouldn't clear. This followed a Windows upgrade and was cured by a video driver upgrade.
For the record by video card has an Nvidia chipset.
