Bats correctly enter the flying animation when they start flying after hanging from a block so this only affects bats that are spawned or reloaded while already flying, which seems to be the case for all naturally generated bats. Bats spawned using a spawn egg or /summon minecraft:bat ~ ~ ~ {BatFlags:1b} correctly enter the flying animation.

Can confirm in 1.18.1

Can confirm on Linux with an NVIDIA GT 730

I made a pack to fix the UV-mapping on all of these

Same thing applies for /particle, if you specify @a the particle will still only be displayed in the dimension the command was executed in, so playsound should work the same way

Except the sound isn't played for players who are too far away, so it shouldn't play the sound only based on the selector, you just use the selector so it won't play the sound for some players

I agree that this is far from fixed, it'd be the same if there was an issue with entities not rendering in fast/fancy settings and saying it's "fixed" because they do in fabulous, even if the higher settings work properly, the lower settings shouldn't be left broken. It makes sense that stuff looks different with different settings, but it shouldn't behave differently.
And since 1.16 has been fully released now, I can confirm this is still a bug in 1.16 and is in fact not fixed

This still happens in 1.14.4

This doesn't seem to occur on my PC anymore (using 1.14.2)

1.14.3 Pre-Release 2 mostly fixes this, as patrols can no longer spawn in a well lit area, so the player can prevent them from spawning in the village

Fishing works perfectly for me, make sure particles are enabled in your settings

Make sure the issue doesn't come from the datapack itself

That might be intentional since chickens are quite small.

You posted this as a Java Edition bug despite specifically stating that you're on Bedrock... You should probably report this bug again in the right section.

This also works with sprinting (doing the same thing than with flying instead of pressing W twice). What I think is happening is that when you leave the inventory, it thinks you stopped pressing that key while you were in the inventory and are now pressing it again, so it thinks it's a second input when it's technically the same input.

Can confirm in 1.14.2-pre4 using Linux

Can confirm on a normal world in 19w03c (happens on Windows and on Linux)

I can confirm that this happens on Linux, and not on Windows

This also occurs on Java 8 and on Linux.

Version 1.12 is also affected, and this bug also occurs in Multiplayer.
