[2021] Fishing Spear leaves behind lines [Investigating]

Still don't see this.   Tried running DX10, low detailed, window,  frame-capped to 30. Skeptical that it's performance related at all since some of you have pretty strong PCs. Tried fishing from a zipline. Tried closing the fishing dialog by clicking button, vs pressing escape versus pressing spacebar.   Seems more likely to be a specific way that you're fishing which is why I asked for video of it starting from not-broken and then becoming broken :)  A screenshot where you've been fishing for half an hour and turned into a tentacle monster is not super useful to us.  Are you using vehicles? Using Controllers? Is it all fish types, all spears, or more specific?

I definitely want to help smash this but we have to narrow down what's causing it first
