Ok, I've got a folder with some photos that I use as the desktop background, about 15 of them. They are set to change every 10 minutes. I have noticed a part overlay of another one of the photos, like the blockiness you get with a poor signal on a digital tv with a bad aerial. Its as if the next photo in the line hasn't appeared properly, if I refresh it it changes and might not happen again for quite some time. Has anyone any ideas as to what this could be?
My graphics are an ATI 6870 with the latest
drivers and software
