Using MultiSample, the code that inspects Z buffer values fail, like for grease pencil drawing on "Surface". It appears to me that all this depth draw/read code is ignoring gpu offscreen entirely. This should be confirmed by Campbell though :) I'm also quite unsure why this code exists, related to other tools that use depth too (particles, sculpt). Good to mark down for our viewport recode.
