Cursor ocassionally stops (input thread stutter)

Bug description

After updating lazer I've discovered a really annoying thing: when playing STD (may also happen in Song Select menu) cursor ocassionaly stops while dragging tablet pen and after some time just "teleports" to the point where the pen is currently located. It happens anytime during gameplay and it is especially irritating when it happens at the end of a song.

Does turning off "high precision input mouse" with this?

Tried both turning off and on this option, but the problem still shows up

For my experience, I have a kind of 2 types of input lags: sudden stop and delayed movements, and luckily I am able to record them. For the type with sudden slow cursor movements, I have experienced for periods vary from a few hundreds of milliseconds to a few seconds. And sometimes coming with rendering lags, but it seems like it would be another problem.

• Sudden stop (blue circles "1" to "2"):

• Sudden delayed movements (near the end of this play, and apparent drop in input FPS is recorded):

From #9283 (the case with rendering lag), it is mentioned that it might be GC-related, but for my recordings, no apparent relationships to GC can be found. In the mean time, I will still try to collect more information related to the lags and delays as useful as possible.

This time. I have tracked on the logs and probably found that it might be related to the slow frames on the threads.

Here, I used 2880x1620 DSR for my 1920x1080 monitor, and 8 font size instead of 12 (default) for the terminals.

Having the stats open probably does that, and is probably not related.

Also having windows displayed above the game, and potentially the game not focused, will not help.

ALso it's not running in fullscreen mode since windows are being displayed.

@BenCheung0422 Please open a separate discussion for your issue (or better yet, self-troubleshoot), it's not the same issue as what is being tracked here.

I am not sure if stats affect that. Also, in the video clip, I used OBS so that the console windows on the back can be rendered in front of the game window. Yesterday, I just captured the moments with cursor movement pauses. I will try to record with stats opened and see if I can capture the moments with slow movements. It is like there is frame loss in input threads in this case. I will open a new discussion (or issue) for this.
