http://ask.fm/Tom94/answer/130513625550 Well, i have same problem, and things dont pop into the foreground, and I can't alt-tab out with "confine mouse to full screen" on either. I really wanna use cutting edge, but this is like the only thing holding me back from doing so :/
Please make a post in the cutting edge forum thread ( https://osu.ppy.sh/forum/t/259747 ) and tell us what kind of platform you are running on, including CPU and GPU. You have to understand, that if we don't get these kind of things fixed it will be broken for everyone once the new stuff gets through to stable.
