[MC-259672] Lag when using elytra

I get this lag when i launch an elytra from Y-256/320.

During elytra descent, And reaching around Y-120 (Surface) nothing renders and i go through all the ungenerated blocks taking me to the void.

integrated server ticks are around 60-80ms. while flying.

and after removing elytra, game goes normal.

there you go. i have uploaded the clip.

while descending towards the surface, the game lags and nothing loads.

ticks went from 9-13 tps to 60-250 tps.

i even got to the void.

Please send me another video for this, your video is corrupt, when I click on the video, it said "Video can't be played because the file is corrupt."

i also can't watch the video

uploaded an mp4 one. Recorded on phone. Hope that one works.

Sorry, but i couldn't upload it properly. I will upload a compressed and watchable one soon.

Let me know if it is still unplayable.
