Confirming this behavior under a somewhat different set of circumstances than those previously listed.

I'm running two heads on a nvidia card with the proprietary driver using Xinerama, and all of my WebKitGTK browsers are exhibiting this. The interesting thing is that, when I run only one head, or on both heads using TwinView (neither being a particularly-appealing workaround), the behavior is no longer exhibited at all. This tells me that I'm getting this behavior as a result of a lack of xrandr extensions on my display, a state common to all setups I've seen this bug with. Given the odd assortment of environments associated with most of the comments in this report, like X over ssh and a Windows cross-compile, my (admittedly disclaimer-warranting) thinking is that a lack of information on the display is causing something in WebKit's GTK widgeting faculty to wig out (only GTK widgets on the page seem to be affected).

I'll be testing this on an assortment of other setups, but, so far, I've only been able to replicate in environments lacking xrandr extensions. Dual-head on an Intel IGP using xrandr seems to work fine.
