When playing WoW in 32 bit mode, the game window occasionally turns completely black for a second or two before correctly redrawing itself. However, the UI elements remain visible throughout.
I have reproduced this problem with a RV730XT card (HD4670 AGP) and a CAICOS HD6450, but not with my RV790. Note that the HD4670 AGP can only run in 32 bit mode, but the CAICOS runs WoW correctly in 64 bit mode.
This is not a new problem (at all!), but I have only recently discovered that it happens with my CAICOS card in 32 bit mode while I was investigating a bug with the sound.
