=) When I forget to kill the launcher indeed it is.

Well, I can definitely say it is not CTRL+ESC for my issue. I got up from my computer and left it sitting in the game for a couple minutes and came back to it sitting at the desktop. I had forgot to kill off the launcher and background process. Every time I make sure to kill the launcher and background updater I do not hit the issue. So I still think it is tied to the Blizz launcher for some reason.

Lol, now that you mention it that might actually be what I have been doing as well... I will have to pay closer attention next time.

I played a bit last night, not sure if it was long enough to trigger the issue or not, but I did not minimize once with the BNet launcher killed. Good find on this work around... Bliz needs to fix their launcher it looks like if it is the true culprit here.

True about window mode... hadn't thought about the BNet launcher. I will have to try and exit it the next time I have a chance to log in and see if it helps or not.

No, this is not a black screen hang issue. Literally it is as if we are hitting ALT+TAB to task switch to the desktop when we have not done so. The system is fully functioning and rendering fine and we are able to task switch back to Diablo 3 without issue. And as the OP stated it seems to only be D3 that is doing this and only since the patch. I was beginning to think I had a gremlin in my system since no one I know has seen this except me on just one of my various systems.

What are your hardware specs? OS?

Curious as I have one system that does this as well with just D3. When the issue occurs for me it always occurs in two's. The second will occur within like a minute of the first minimize. Then all is fine for X number of hours before it again happens two times. As you say rather annoying issue thankfully I do not play on HC as I have died many times to this issue to date since 2.0.1 went live. :/
