No, the bug happens even if you aren't crouched which is why it also affects End Crystal PvP especially with slow falling. You just need to throw the ender pearl on the ground.
Seems like my bug report was misunderstood. I made this bug report super unclear, mods is it ok if I write a new one that's much better?
Like I said in the bug report, your latency and the server lag shouldn't decide on how much time you get. That is not fair.
The switch off-hand is also important. When you hold the key for that it makes a lot of noise especially if you do it holding armor pieces. You can't hear the noise but other people can.
That bug report doesn't have any solution that keeps end crystal pvp skillful and fair. It lacks a consistent delay for all players regardless of their latency or server lag. It also doesn't have a video demonstrating what that consistent delay could be, like the video I made showing how different delays actually look like so people could see what options there are. So fixing it using that bug report won't make end crystal pvpers happy.
It's gonna be annoying whenever you're fighting someone and your pearl lands on your opponent's wind charge or your own wind charge. That's why it's not worth keeping the bug if I think about what you've just said Ruukoto
