I play on my server which has origins and I am an elytrian. We use a datapack that adds /trigger home and /trigger spawn allowing us to teleport there (vanilla tweaks). I've noticed that whenever I teleport to a another dimension (e.g. /trigger spawn while in the end) I lose the ability to glide until I open up any gui that isnt the inventory. Not 100% sure what is causing this but its a weird bug.

Can concur that this happens, has gotten me killed in the end a few times

Does this problem also occur if you use the regular portals?
