Comment 108 for bug 973096

I think this bug is related to anything that uses the graphics card for accelleration, be it 3D games, Flash, Blender or Chromium. It also seems to only happen on specific graphics cards, and I'm not 100% sure they're all from NVIDIA. I had a similar thing happen on my laptop with an intgrate Intel 950 card, just after 12.04 release, but that problem vanished soon after. I know there was some issues with the Intel graphics driver on release of 12.04, so maybe that is what fixed it. I don't have this problem at all on

I think the only way you can re-create this bug is by having hardware that causes this bug, and using any software that uses hardware acceleration for a short while. It doesn't seem to be triggered by any specific action beyond that. I get this consistently on Quadro FX 3700, but there is no one thing I do to cause it, and have even had it happened once when I stepped away from the computer for a short while. Generally I have Chromium and the Gnome terminal window open, but have had it happen with just a terminal and Blender.

I've done multiple clean installs of 12.04, and I've done a clean install of Fedora 17 with Gnome 3, and had the same bug happen there. It seems like a tricky bug to figure out, as it's not caused by any specific action, other than a combination of specific hardware and using hardware acceleration, and possibly Gnome.
