That looks like an accessibility setting or a corrupt font in addition to the buttons. On the Mac they put it under Universal Access to put white on black. Try steps 12 & 4 from the below KB article (even though the problem is for something different) and then check accessibility settings on your video card software. If that doesn't work, I'd first uninstall the Video Cards completely to remove all drivers and then re-install as if you just put a new card in. And if that doesn't work, last step is to go into DW Help->De-Activate and then re-install the software.
Tried both of those things, Tried reinstalling, no help.
And... It's not just nVidia, I switched to Intel processor graphics HD 3000 and it did it. Back with CS4 I went to an ATI card and it never did it but my GeForce cards would. Maybe I'll order an AMD card. Driving me nuts.
