Got it... with the Eraser tool, switch off opacity and gloss in the toolbar at the top, set depth to 0 (RMB), and voilá! Makes sense.
Yes, newbie here... =)

Hello!
I just had the exact same problem - the strokes had an offset from the surface.
I think I just found out what the problem was - there's been a superfluous duplicate of the object with a slight offset still in the tweak room, which was invisible in the retopo room. The strokes however were painted on the invisible, shifted object, too, which looked like a strange offset.
I just deleted all layers in the "Surface Materials" panel in the tweak room (??), and for some reason the duplicate was deleted, too, and the problem was solved. Don't ask me why, I'm a newbie and I still don't even know how to deal with the tweak room correctly.
