Hand animation sometimes plays for a second time with high ping

I disagree with the whole .. If server is lagging part ... this occurs regardless of if the server is lagging or not

If the server is lagging it will cause artificially high ping lag
But also if the server is far away from the client, there will be high ping lag

The title should be changed to "Hand animation sometimes plays for a second time with high ping lag"

The hand animation plays for a 2nd time regardless of latency. I can run a server on my computer an it will still occur an there is no latency at all

My internet speeds are about 300mb/s download and about 200mb/s upload and it happens when on any form of multiplayer whether it be through LAN play, hosting from my PC or my friends who has faster internet speeds than myself, it also happens on realms. This only relates to my situation in the fact that it occurs online.

As I already noted above, I was able to reproduce this in singleplayer too.

The bug isn't high ping lag
Its the fact that the server tells the client to do something that it has already done
High ping lag only makes the bug visible

A laggy server can cause artificially high ping lag
Just cause your download is fast, doesn't mean your ping is low
Check your ping before you connect to the server to see if its high next time

If your ping is low enough the two hand animations will overlap each other and you will only see one

Again the Summary should be changed to something like "Hand animation plays for a second time (only visible with high ping lag)"

A laggy server doesn't cause the bug, only makes it visible

It is 100% client side, server did not take action yet but client keeps trying to preform this action, opening chest is a great example

If I'm connected to a server (LAN in this case on a different PC), the ping is next to 0ms
Opening a chest is instant (and plays the hand animation once)
If I unplug my ethernet cable, right-click the chest, the hand animation plays once
I plug the cable back in, 2sec later (once the network has sorted itself out) the hand animation plays a second time and the chest GUI is opened

This happens with other things like placing and breaking blocks etc

While there was no internet, the client only ever plays the animation once, when I right-clicked
It never tried to perform the action over and over again

Same problem here, I can reproduce it by opening a local server and connecting to 127.0.0.1.

^{EDIT: After installing 64-bit Java I see that the tps have normalized and the bug disappears. Before (with 32 bit java) the tps were very low.}

I can confirm, this bug happens mostly if player has high latency

I tested with a friend with higher latency than me, while I didnt do the animation twice, he did and I could see him do it. So you can see players playing the animation twice aswell.
