Not sure if it's only me but when I tab out to open the Xbox menu or when a notification pops up on my screen (like an invite or other random notification) and go back into the game the whole thing begins to have framerate drops and stutters alot for about 10 to 15 seconds before going back to normal.
(in the clip I'm using actions and stuff and I've tried to fix it without using the pack, lowering my render distance and graphics and the stuttering stuff happens)
ts wasn't resolved btw
