Bugged slopes in carmack with texture resizing enabled

It seems that slope rendering is broken. Haven't checked since when though, I rarely use software so I only noticed it now on recent devbuilds.

Looks ok to me in a build from today.
Of course I do not have the maps the screenshots are from.

I'm seeing it on literally any map with slopes ever made, but ok.

If it's not happening on your end then this may be another annoying gcc mis-optimization issue. I'll rebuild with clang just in case.

Edit: Nope, same issue with clang. It also happens with debug builds.

Double edit: Doesn't happen with a clean config. I have absolutely no idea what caused this breakage.

TRIPLE edit: OK I just nailed down what causes this. it's the opengl texture resizing. If I toggle it off the slopes draw correctly. Let me update the topic title.

Bumping this thread just to say that I'm also seeing this issue on my machine. Same problem (strange stretched appearance on slopes) under the same circumstances (GL resizing on for textures).
Two questions:
  1. Can somebody else reproduce the problem?
  2. What file handles the GL resizer? I might try to take a stab at it...
