Apparently if you delete all launch options the bug goes away.
I'm getting both of these, both before the drop (much more often) but also randomly during the match, Sometimes I get some visual glitch in the middle of the screen which covers half of the screen and obscures what I'm shooting, sometimes I run and see half-3rd person (I see my character's teeth). I'm playing on Nvidia GeForce Now and this is purely S6-related, has never happened before. Eagerly waiting for a solution, though it seems not many people encounter this issue, had a bit of a hard time finding it online.
OP here. I noticed the exact same issues as you described. Not only in jump ship. But the other stuff only happens in Kings Canyon for some reason.
I've had it happen in WE during the first week of the season, as well. All of it. The bit before dropping is happening the same amount on both maps, but the rest seems to be more aggressive on KC, indeed. Either way, I doubt it's map related, but I did think it might be GFN related. Maybe it's just a visual bug. Unfortunately, I can't use the "repair" option on Origin if I'm using GFN. It's either in or out and the game is preinstalled. Otherwise good stuff, if all went according to plan.

A "solution" is aiming down-sights. It helps when looting or watching inventory, but not with the pings or when walking.
Remove cl_showfps launch option, thanks @gubergren @B4ddo
I had to remove cl_showpos too for it to work, cl_ options are problematic.
