Minecarts slow

 

Minecarts are much slower than expected.  Traveling on a stretch of track that should take 4 minutes, takes 12 minutes.  

 

Entire game has been glitchy on Realms since 1.14.3 was released.    Also experiencing the visual "tearing" or whatever it's called that other Mac users experiencing. Also food takes multiple attempts to eat before it works and is consumed. Also blocks of all sorts are reappearing after they are broken.
