%%%--- Operating System, Graphics card ---
Linux Mint 14 x64, Windows 7 x64; GTX570

- Blender version with error, and version that worked ---

with error: r55316 - r55451
worked: r55315 and earlier

- Short description of error ---

GPensil doesn't respect Surfaces and won't stick to them right when:

MultiSample in viewport is enabled
You has selected some elements in editmode (like select some vertex or edges)
You rotate viewport (camera of viewport?) after selection mesh elements

Video about it: http://youtu.be/I73tcm-sMzo

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

Make sure you have multisample enabled (i had x4)
open default scene with default cube
Make new GPencil layer and set his draw mode to 'Surface'
Go to default cube editmode and select some vertexes by mouseclicking
4.1/2 (Optional) leave editmode
!!! Rotate viewport (change foreshortening, сhoose a different viewport-camera angle ) !!!
Draw some GPencils balls of yarn over the cube (with pushed 'd' key by default)
See? It doesn't align to surface (

%%%It look like some problems with depth's getting, but i'm not programmer and don't know%%%

%%%Confirmed. But this code is confusing here... it uses the ED_view3d_autodist() feature (for viewport manipulation).

This whole depths updating pipeline seems to be unique (even though similar for sculpt or particle drawing), and ignores gpu offscreen entirely.
I've added a fix for grease pencil now, also seems to work for "3d view autodepth" feature now. But the full implication of this code is better for Campbell to give a final review for.%%%
