Well I remember onetime I fired up JK1 shortly after I'd upgraded my drivers for my video card and there was all kinds of crap appearing on the screen during gameplay. I thought "aww crap" because I felt they wouldn't support such an old game anymore. But a few updates later it was fine again, so they did fix it.
I would just keep updating and hoping they'll fix it. You could also try sending the company that puts out the drivers feedback/support email and request they fix it after explaining the problem.
