This minor graphical error will persist until you enter and leave water again.
Reproduce:
- Give yourself the "fast" permission.
- Swim with the "use" key and mash yourself into the ground to take damage.
- Swimming acts like flying, and allows you to speed upwards and downwards unreasonably fast while you hold the use key, but does not disable fall damage.
- Is this another bug in itself, or just a strange quirk?
- You can also use this to leap faaar out of the water like a dolphin. \o/
- Possibly easier if the player physics speeds have been modified in minetest.conf, I am uncertain the threshold you have to be going to take damage from this.
- When you respawn, the oxygen hud should have disappeared, as you now have full oxygen again, but it didn't get an update from the server telling it specifically to do so, so it persists.
