System Information
Win 7 x64 (MAIN_DESKTOP_PC-_system-info.txt)
Win 7 x32 Home edition (laptop lenovo) (Laptop_system-info.txt)

Blender Version
Broken: at least since 2.69

Short description of error
https://www.youtube.com/watch?v=1bYJmhwCECI&feature=youtu.be
panting causes to wrong lines projection.

Exact steps for others to reproduce the error
Blend file: paint_bug.blend
1-open the blend file,
2- maximize blender if it starts restored window, using a 1920x1080 monitor resolution(this is very important)
3- try to paint as in the video, in the same place

Note: Before submit the bug i try to upgrade the desktop pc video drivers, for some reason i could not, but i connected the laptop to my main monitor (to get 1920x1080 res) and fails the same way, it is an other machine drivers even video card(info attached under System Information)
This error happen to me often but i was never able to get a test file it was too random, this is the first time i nailed the error. Hope that the info be enough.
Also notice in the video if the view angle its change a bit it works fine, as difficult as it seems to get the break angle it happends quite often.

someting i realized, at the moment of testing if you are using windows, hide the bottom desktop tasks bar or move it to a second monitor, the bar makes the blender window a bit smaller and the test file no longer works.
Again seem extremly difficult to get the angle, but i accidentally trash several textures because of this before realizing what was happening.

Hi, I can't reproduce this here. There were too many changes to the paint code for 2.72 and recently we also fixed a bad bug with seam detection - which is what might be causing the issues there. Can you try a recent version from builder.blender.org and see if it works for you now?
