I'm generally safe from this error until I alt tab - it hits me while i'm doing things while alt tabbed, like looking something up on chrome, causes my video driver to crash and recover (this error will sometimes pop, other times the client will just freeze up and i have to end process it and start it again). since i like to alt tab to look things up or check on things quite often, it's pretty annoying. started when i got a new and better pc this fall, and thus switched to the DX11 client. given that it works when i'm not alt tabbed, i'm not prepared to switch back to dx9 client at this point, but it's still getting REALLY irritating.
