ZDoom

As found here, zdoom has some kind of problem dealing with 1x1 textures, if you increase the size of the texture the problem is gone, but with 1x1 textures, or they get glitched in the render scene or they crash zdoom.

If you can't see, the blue wall is gone and there are just some blue dots on it

Also, if you look around, the game will crash, with bigger textures the game will just work fine.
