Teleport location glitch

Whenever I /tp to 300000 — 300000 the entire world will look super glitched and i cant move. it kind of looks like every 1 or 2 blocks have disappeared and I am inside a block! I /tp to 290000 and everything's completely normal. I don't know what is wrong but something is.

 

p.s i do not have any photo's     #sorry!
