This issue started just a few days ago seemingly out of nowhere. When it happens, it's very brief, only for a split second but it makes me fail almost every map I play. I recently got a new mouse and mousepad thinking it was because they were very worn down, but I soon realized that the cursor freezing was only happening when I played osu, not other games. This could be because osu is the only game I play which involves moving my mouse so vigorously, but I'm honestly unsure. Really sucks because now I can't enjoy the game anymore 
Before this started happening, I did not change any settings. I'm using raw input and have mouse-acceleration turned off. I'm playing on osu! stable. And also I'm not using any external programs that change settings of my mouse. I took a mouse polling rate test and I had an average of 140hz. Not sure if that's enough info, but if you think you need anything else to help me lmk.
Here's a clip of it happening:

It's kinda hard to tell, but as I tried moving down to hit the red "5" circle, my mouse input just didn't register for some reason so I over aimed everything that came after and just failed. I missed the red "4" circle because my aim just wasn't warmed up, not because my inputs failed.
And also here's a second clip:

As I start the teal new combo, my cursor just stops and I have to kinda jump it ahead to the right in order to catch up with the stream.
