[Crash Bug 1.516] DX Error when Alt_tabing

Interestingly, i get a similar error when alt tabbing, but only after the newest patch. 

Please try the new 10.8 catalyst that ATI released today.

I have a Nvidia card with up to date drivers, and I get the DX error crash occasionally when alt tabbing too. I don't recommend alt-tabbing until they figure that out. Play the game in windowed mode at your desktop resolution. It's indistinguishable from full screen, except you can pull up desktop elements without alt tabbing.  I haven't had a crash in over 24 hours since starting to play that way.

I get the same issue occasionally on an Nvidia card.

The pertinent bit seems to be:

DebugMessage:  DX Error: Invalid call
Debug Message:  ERROR: Failed to set ambient color to -1 in ::SetAmbientColor
DebugMessage:  Error flipping back buffer to primary buffer.
DebugMessage:  Invalid call
DebugMessage:  Main Shell terminating normally

Figured I'd share, in case more data helps.

Same for me, just like Spyndel. I have a 8800 gts in a laptop, and it gets this alt tab issue every 3rd or so time. Drivers are up to date. It's annoying, but Windowed mode fixes it temporarily. hope it gets fixed soon; this laptop has this issue, my other one gets a white screen

The new 10.8 catalyst that ATI drivers make things worst not better, now after updating the drivers, I now get all sorts of graphic corruption (blue screen, black screen, etc.) during tactical combat!!!
