Been using:
1. Your sample without -noautoload
2. HD with -noautoload
Just tried 7b16433 now with your sample with -noautoload. All cameratextures black.
Now looking for the most recent commit that doesn't do this.
8da1b5c is okay so far.
EDIT: 4f4d10c is also good. This seems to have started in one of the Jan 4 commits.
EDIT: It's either 980977d or the one right before it...
EDIT: Confirmed it is
f10ded7 where the bug first appears.
(The software crash happens on 4f4d10c and 3.7.1 as well, so I think we can pretty safely say it's unrelated.)
EDIT: this bug doesn't seem to happen at all on my Win7 machine running the 32-bit devbuild (gzdoom-g3.8pre-148-g32cf79c51). Can't test 64-bit.
EDIT: did a dist-upgrade and restarted my computer. Still got the black camtexes.
