Alt-tab while in exclusive fullscreen takes longer than expected #17381
Description
Reported twice now, hitting alt-tab while in exclusive fullscreen mode seems to switch display modes more times than required. Will require some investigation by someone who can reproduce this to find out the origin of the issue (osu! / osu-framework / sdl). Apparently stable does it well, for whatever that's worth.
There have been a few recent issues made SDL's end surrounding the fullscreen logic. This one for instance may be related to what users are seeing here.
Discussed in #17380

I've had this problem ever since I tried osu!lazer, but didn't bother asking as I didn't find this annoying. However, it started to bug me out nowadays that I'm playing the game more often than osu!stable.
Unfortunately, I didn't have a good enough computer nor device to record, but I thought the video is enough to give an idea of what's going on (had to put it on YouTube due to GitHub file size limit).
In case it's not clear, I was simply alt-tabbing between Notepad and the game, which caused both my displays to flicker. I'm not sure if this is a problem on my end or the game, so I didn't immediately create an issue.
