Sorry to hear the patch didn't work, but am I reading your comment correctly that you are playing the game through a browser, and not the windows exe version? You said it worked if you kept CiC in a fullscreen browser tab, so I'm just curious there, because if that's the case then it I would also suggest running the exe version instead of the web version and seeing if that helps. Otherwise, I think you're stuck with your Frankenstein solution you described there, because I'm stumped with this one.
