As seen on Ulraf's Sunday stream (-:
Can somebody please try to confirm my vsync work-around?
Still an issue in 1.14
Going into video settings and disabling vsync seems to fix the problem for me. I remember that this was the fix for a similar issue back in version 1.7
Is it not just drowning?
This behaviour is also caused by self-moving piston contraptions when ridden by a player.
I can confirm that this is still a concern in Minecraft version 1.9
Additional information: This is only a bug at night. During the day, the respawn point is set even if you would be too far away to sleep.
