Glitches in dialogs

[Burbly]

Just installed dolphin (3.0). *All* the dialogs are glitched -- for example:

The basic problem seems to be that when I switch tabs, the controls in the new tab are rendered on top of the controls in the old tab -- i.e. the dialog background isn't rendered at all.

Specs:
XFX ATI Radeon 5770 HD 1GB
Core 2 Quad running XP Professional 32-bit

Any help would be much appreciated!

Edit: same problem happens in v3.0-759.

NM -- fixed it by rebooting.
