Did you see this on Mac or Windows?
I saw this briefly last night with one of the last few nightly builds on Mac OS X. It went away after reloading the page a few times, and I have not been able to reproduce since.
I also saw exactly this behavior this morning, on Mac, on multiple webkit bugzilla pages (buttons and multiple popup menus were affected).
I wonder if it's an uninitialized color being used somewhere?
