Description of the problem

Sometimes, when I draw, mypaint goes totally nuts.

cursor drawing is fine, just the stylus seems to be going batshit crazy:

I'm using a 2 button surface pro 3 stylus, and this problem doesn't seem to happen on mspaint:

I actually have no clue how in the world I trigger this, and it fixes itself after a restart. Anyways, I thought it might be helpful if I posted this issue.

Basic system details

MyPaint version: [1.2.1+gitexport.bcf5a28d]
Operating system: [Windows 8.1Pro]
Desktop environment: [Windows?]

Steps to reproduce

[☞ Tell us how to reproduce the bug in clear, numbered steps.]

1. Start MyPaint
2. Draw

(I actually have no clue how to trigger this, only that it happens occasionally)

Also, the problem only shows up on start of mypaint, so it won't do this out of the blue if it's already working properly.

Disconnecting all peripherals doesn't do anything :/

Huh, it actually fixed itself without restarting my computer this time. Just restarting mypaint somehow did the trick.

@kelvinwop

• Is this still happening?
• Is this happening with a recent alpha build?

I suspect that this may be a duplicate of #177. There's some similar glitchy output from Surface Pro devices. Can you re-test and see if it glitches after a touch event?

Interestingly, I can draw with my finger without making the jagged lines. Just the stylus triggers it.
