Screenshot of bug in Amnesia

Some games have some sort of visible wireframe, or an outline visible when
r300g is used (softpipe does not have this problem). I'm pretty sure this is a
known bug, but I haven't found any open bug reports about it.

This bug is very noticeable in the game Amnesia (where the screenshot is from).

Is it known what function/effect the bug is in? If not, considering how
prevalent this is in Amnesia, maybe  Edward Rudd could shed some light on this?

This bug is r500-only as far as I can tell.

I have just found a way to trigger it very easily: enable offset mapping in
nexuiz. If you disable it, the problem will go away. Given this fact, I believe
it's a bug in our r500 fragment shader backend.

I have a similar problem with sauerbraten on my RV530, with both r300 and
r300g, see also bug #25710.
