After one of the more recent updates, I've been having issues Alt+Tab-ing to separate windows. Usually, it's flawless and if you quick push Alt+Tab it'll open the most recent previously open window, or if you hold Alt+Tab it'll display all your currently open windows and let you pick between them, but at this point everything lags, and then it releases and osu! is still present, but it's like there's another active window so the frames are lowered, but I need to push Alt+Tab again to pick the window. Only happens with osu, other games or full screen applications work fine to Alt+Tab.
I usually run experimental build, but I did try stable build to see if that would fix and it doesn't change anything.
osu! version: 20180510.4 (latest)
