Description about the bug: When you are on a boat (probably with a Villager cause I was getting one at the time) and you exit. I was lagging out in a repeating motion. Say like when you are falling through the air you glitch back and repeat.
Possible Workaround: Ride on the boat again (really hard as you're camera is glitching) then exit away from land then hope you're lucky and Minecraft dosen't torture you again.
Possible Reproduction of the bug: You exit from a boat near land (with a Villager probably)

Can confirm 19w35a. It happens literally every single time. The boat disappears too and I have to log off and log back into my server to fix it.
