I downloaded the new version of Krita. Whenever I sketch or make quick movements with any of the brushes, the brush stalls for a split second and snaps away from my line, making it really hard for me to sketch. When I move slowly it works just fine, but whenever I try to make a quick line it stalls and it's very annoying and jarring.

Please tell me how to fix this. I want to start digital drawing and I can't really do that with this problem looming over me.
Thank You!

That's caused by instant preview on small brushes: https://docs.krita.org/Instant_Preview

I turned it off and now it's fine! Omg Thanks!
