I can't easily say why you see a GLXBadDrawable error. Are you using compiz? yes to the last one...but I've tested it with metacity active...no change. but if you say it's on the driver side...hmm...don't know, I've never seen that error nor had I ever glx errors (only when (indeed) the driver wasn't installed correctly. But I reinstalled it now and rebooted without a change...
