Osu: Cursor behaves strangely after returning from multitask

[Morilli]

Describe the bug: When alt-tabbing at the same time that a beatmap is starting, the pause menu immediately shows up (as expected), but alt-tabbing back in shows some distorted graphics (see video).

I am using Windows 10 Pro x64, build 17763.404.
My graphics card is a nvidia geforce 1060 6GB.

That looks like the cursor trail trying to interpolate over some weird movement. Very interesting.

In case that's helpful, a git bisect shows that the first bad commit should be 1e36962.

This seems to no longer happen since b9a39fb7880b3dfa818a0e3e59f89343b2241d51 judging from a bisect. However, I don't see an obvious reason why this was fixed, and is likely still broken. Might still be worth looking into.

What does this mean? Can you test on master more and confirm broken or not?

[nyquillerium]

It does not happen on master, and hasn't happened since the commit mentioned.
