What is that visual bug ? (Solved)

[Spowmtom]

As I was making my map, I found this visual bug. I'm new to Doom editing, but I'm pretty confused as to what those pink pixels are. They're not part of the texture, as the other side uses the same texture and doesn't have those distracting artifacts.

I would like to fix this, how ?

Thank you for your time.

It's the tutti-fruitti effect. Does that linedef have a vertical offset on the texture?

Seems like the NUKE24 texture plays funny when offset by a great amount, it doesn't loop well.

Considering the layout of my map, I fixed it by just getting rid of that little gap.
