Hm... they might be due to the fix affecting the positions of the
radiosity samples gathered during pretrace. But I'm not entirely
satisfied about this yet.

If that is so, then the conclusion I'd draw is that I probably messed up

fixed it during texture refactoring without realizing and/or remembering it.
