Hello

When I draw a line that is thin or thick the beginning of lag tracing.
I am on Windows 10
32 go memory
Krita 4.2.1
Tablet Wacom intuos pro
gaphique card: NVidia 1080 gtx.

Can you help me ?

Lu :c)

Check whether https://docs.krita.org/en/user_manual/d ... s-of-lines is the case.

Thank you boudewijn

But I also have the same problem with the mouse .

Maybe the "brush smoothing" in your Tool Options is set to "stabilizer"? (if so you can change that to none, basic, etc.)
