[2.2.13] Scrolling Wall Textures may get warp'd after awhile in OpenGL.
After some time goes by... some scrolling textures on FOF walls will get warp'd but then revert back to normal after it happens. This doesn't seem to happen in Software, though.

From left to right:
Middle Wall, FOF Wall (It be Solid or Water, prob others), Floor Wall and Ceiling Wall.
What's interesting is that after making an example map in binary... the middle wall texture gets warp'd alongside the one on the FOF, unsure if it has to be due to how big the wall has to be in terms of height or something.
