As of december 3rd the trails behind any throwable can randomly be a bit janky and distracting on the eyes, and i remember how the game played before said update, so to fix this bug, definitely start with looking at what was changed in that december update.
Look at any pre-update gameplay and you'll see these trails dont glitch out and fly in diagonals on your POV screen, and definitely none of the goofy lines the morrgen meltdown did!
Hope to see this addressed <3
