When alt tabbing out of Diablo III and then back in, the game experiences a host of issues. I've witnessed a failure of the game to load in assets (models, textures, etc.), sound failures (stuttering, cut outs, failure to play sounds), control failures (failure to recognize input), among other things. Alt+tab will frequently require a restart of the game to correct these errors.

Could be several reasons for this to happen. I do have some steps for you to try that may help when tabbing back to Diablo III.
• Run the Diablo III repair tool.
• Set Diablo III in the video setting to windowed (fullscreen).
• To be on the safe side make sure Windows and the drivers in the computer are up to date.
• Please run Diablo III in 32-bit mode.
If there is still issues with Diablo III loading back up, post a DxDiag. Paste the DXdiag into the post, select and highlight everything you just pasted, and hit the "code" button (</>). That'll make the information much more readable.
