The required information;
Game version is 6.20 with all dlcs and no mods. English
Game start i discovered this on was the teladi trader but it appears present in all
z-fighting textures on the vent, aft starboard side

decals disappearing 1-2 steps closer to the ship


It seems to be more dependent on the angle of the camera rather than the distance from the ship


And finally, i'm pretty sure these aren't necessary in this instance but for the sake of completeness I'll include them anyway. (These were uploaded to my personal discord server so when the links are clicked, the text files will be automatically downloaded. if another means is preferred i can upload them elsewhere)
