Description h1477978 2016-09-30 01:02:14 UTC
when using a mouse, the stabilizer feature of the freehand brush will cause the cursor to quicky snap to a seemingly random point (although they noticably tend to be in a small radius of each other, but often change where this radius is). Changing settings doesn't seem to prevent this effect. Changing brushes also doesn't seem to stop it.

Reproducible: Always

Steps to Reproduce:
1. Select the freehand brush and open the tool options panel
2. Set the dropdown box to stabilizer
3. Click anywhere on the canvas with the freehand brush tool active

Actual Results:  
The brush quickly snaps to a seemingly randomly selected area and back creating a line.

Expected Results:  
The cursor should remain where it is and create controlled strokes

The mouse I'm using has mouse acceleration, and I use the mouse and touchpad settings to override it (this may not make a difference, but I believe the software compensates for hardware accel, so I thought it was notable).

Hi,

Thanks for your report. I can confirm the issue. It doesn't happen when drawing with a tablet stylus, only with a mouse.

Hi I have the same problem also I have noticed that even when I'm using tablet
when I press "V" to make straight line my stroke snaps to left upper corner of the canvas
and return to the start of my line.
