Thanks Retrofan. I get exactly the same behaviour as you. With Highgfx after about an hour the glitches appear. If I open up my case and waft air around it does seem to make things better. I don't want to contradict Jens but this happens with other screenmodes besides the ones that push the chipset. For instance it happens with DblPal and I have been using DblPal on the RGB port for years with no artifacts. What is peculiar is that we are all seeming to have no problems with SuperPlus (I have left it on for 3 hours+ with no glitches). Maybe the config tool will give us something to tweak?
