I am using Gimp 2.8.14 on Ubuntu 14.04 and a Wacom tablet (Intuos 3 6x8).

My problem is that I cannot make a smooth stroke even when I check the Smooth stroke in the Tool Options panel. When I do that the problem is less evident, but is still there.

I believe the tablet is not the problem because in Krita the problem does not appear.

Exemple of me trying to write my own name with the pencil tool and a stroke with the brush tool:

Here is the link if you cannot see it:


I have already uninstalled Gimp and installed it again and the problem persists.

Can you please give some directions to solve the problem?

Thank you, very much.

  • Did you try with different setting for Smooth stroke quality and weight?

    This looks like your stroke is snapping to the grid. Can you make sure that this isn't turned on? Oct 17, 2015 at 9:40
  • @Takkat, yes I tried different values after checking the Smooth parameter and I had to put both at the maximum values to have the desired results. Oct 17, 2015 at 22:14
  • @MichaelSchumacher, your answer solved the problem. The View > Snap to Grid option was turned on. As soon as I turned it off, the problem was fixed. Thank you very much. If you want, you can create an answer to this question and I can mark it as solved. I believe it counts points for you and your reputation. Oct 17, 2015 at 22:18

As Michael Schumacher (@MichaelSchumacher) pointed out in his comment, the

View > Snap to Grid

option was turned on and, as a result, interfering with the brush strokes.

Just turn it off and everything is OK.

Do not check the "Smooth stroke" paramenter at the Tool Options panel, because it will slow down your machine a lot. I tried that and, to have the desired result, I put the values at the maximum levels. I could not paint freely after that.
