Recent problem: Brush stroke gets "jerky" (not pixelated) / Uneven stroke!

[froufroufrou]

I'm not entirely sure when this began, maybe the most recent photoshop update, or the one before that?

When I draw with the brush tool in photoshop, the lines become really jerky and ugly - like my hand was shaking like crazy, which I'm pretty sure it isn't. See picture below as example (zoom to see better):

And here's the actual psd-file.

The file has a large dpi, so it isn't pixelation. The spacing of the brush is also 1% so that shouldn't be the problem. Some of my illustrations from fall do not have this jerky line:

And the psd-file for this.

Also I notice that it gets jerkier when I draw in 15% size-mode versus 100% size-mode.

I hope someone can help me fix this.

Have you got the Size Jitter turned on and up in the Shape Dynamics?

No everything is set to 0% in shape dynamics.

It seems I solved it by either updating my cintiq driver or resetting photoshop to "factory" settings.

Glad you got it fixed.
