BTW, disabling hardware acceleration in Firefox didn't cure the problem. I hit "Reqly" here and the response box still misses displaying lines or has other garbage from the screen in it.
I remember years ago having a problem something like that with the Intel GMA drivers but it was a *long* time ago so I don't recall the details. I think I solved it by disabling compositing at the WM layer. Is there a setting to disable "Desktop Effects" or something similar in your particular distribution's settings panel? (When it comes to my desktop I'm a grumpy old coot and don't want transparent shimmery "look at them shake when I drag them!" windows so shutting that off is still something I do to this day whether it works or not.)
The other thing I'd probably try, given the relatively recent vintage of your hardware, is seeing what video driver you're using and switching to the other if that's an option. There are "binary" and "free" options for both Nvidia and ATI cards; Unless you're religious, which you're clearly not, the binary driver is usually the optimal choice with the Nvidia chipsets but there's some gray area with ATI cards. (Not much though, since ATI tends to be pretty aggressive about knocking cards off the supported list for their binary drivers as soon as the open-source driver works for them; the overlap is usually only a generation or so.) Honestly, since I don't game on my PCs, I prefer machines fitted with ATI cards old enough to be well supported by the open source ATI driver; it seems to be the least troublesome and do the job adequately. Because of Nvidia's "we don't document the hardware without an NDA" policy the open source driver for Geforce cards is probably always going to be broken to some degree or another. (Sad but true.)
