Input thread blocking causes mouse handling stutters on windows

Many reports of this recently, to the point I believe something may have regressed.

Hi, I made the https://github.com/ppy/osu/issues/27208 issue. I have since found out that this is related to my laptop keyboard, and isn't dependent on the touchpad. I've had typing lag-related issues in other programs, so it's possible that issue might not be entirely osu!lazer's fault. Though it's still worth noting that it doesn't seem to happen on stable. Also, it affected me for a while before I got around to reporting it.

Basically what I'm saying is: given the circumstances, my issue might be unrelated from the rest of those listed here. Hopefully this is helpful, sorry for any confusion or problems I may have caused. If there are any questions I can answer, then don't hesitate to let me know.

I believe the five issues above are all related to tablet pen and the last one (the mention to this issue) is related to mouse. I think it is generally cursor handling problem.

Probably keep this open until a fix has been confirmed.

Creator of ppy/osu#27448 here, the new April 12 Update seem to lessened the frequency of the stutter (included other rulesets, ie. sentakki) . Unfortunately it's still unresolved with several time it can be very noticeable and caused a FC choke.

Not sure about other people though ( need more confirmation ). But hey, at least I got 50/50 chances this time for me.

The update has not changed anything yet. This will likely be fixed or significantly improved in the next release.
