This doesn't have anything to do with OpenGL, I don't think. On a brand new, pretty much virgin 8.10 install on my Dell D630 laptop with an Intel GM965 video chipset, I had this happen when returning from the blank screen saver. It doesn't happen everytime. All I see is the background and the mouse with no menus or windows. The mouse responds normally, but the only recourse is to power off the computer and reboot.
