Renoise 3.2 on Windows 10:
When in fullscreen, pressing Alt-Tab to open the Task Switcher, an odd UI appears instead of the normal Windows one.
That is weird. I don’t see if it simply maximize the program, but using the Renoise -full-screen option gives that “Win 95” alt-tab thing.
That’s clearly not a bug, but a feature! 
That’s super weird indeed. No clue why this happens, but I agree that it could be a feature too
