Normal line start to waving after some time

[Matte_97]

As title say, when I'm drawing even if I try to be perfectly right, my line start to create constant little wave and it's frustrating.
The solution I've found is to draw fast but it isn't normal..

It’s behavior of all graphics tablets and monitors. You can’t draw perfect line if you draw it slowly. Draw it fast or use line tool for perfect lines.
