Comment 4 for bug 152838

Thanks for checking!

I don't have special effects enabled. It is with the Intel 950 adapter, using the intel (modesetting) driver.

I hadn't tracked this for a while since I switched to the window selector applet so I could get my work done. I just tried the window list again, and the problem seems to have gone away. I'll switch back to the window list now, and if the problem recurs, I'll post another message. If not, I suppose this should be closed.
