Texture or lindef problem

[Ice]

Well, recently I've been trying not to procrastinate in making my making my map with the upcoming contest. I discovered a problem that seems unrecoverable. I don't know if this might be considered as a "hall of mirrors" or a "slime wall" because I found the glitch in openGL. It may be something else, but when I actually some near the wall, the glitch goes away. Here's some screenshots:

Here's where it happens-(disregard the redwall)

And here's when I get closer-

Is there any way to fix this?

That happened in Glaber's map in the last contest as well. I'm pretty sure it's an OpenGL bug.

Well it appears in software mode too.

Link. I'll try and fix it.

Added another sector there. It most of the time works.

I'll try putting another sector there to see if it works. I can't publicly release it, but I'll pm the download link to whoever is completely sure they can fix this.

EDIT:I figured out the problem, my thok barrier was too big. I forgot to resize it around my level... silly me!
