How do you fix sectors/walls flickering?

[Kaido]

When making a boom compatible map , I sometimes see sectors or walls just moving weirdly and start to do some weird flickering effect . It only happens when I start moving , once I start moving the wall start to act weirdly and move in a weird flickering effect.

Could you give pictures? My best guess would either be a hom (happens when you dont have textures on a wall in a port with software rendering) or some sort of weird node builder error but I couldnt really be sure without looking at it

Looks like math imprecision. Try splitting the line into shorter lines.
