Unloaded Chunks and Game Hanging

I'm not sure if this came in with 1.13.1 or 1.13.2

 

Around 25% of the time when I load into my single player world, multiple chunks will not load in - the game sort of hangs (I can move but not interact) and then the synthesizer/loading animation appears over the top of my game world (doesn't drop to white screen, I can still see world behind it.)

 

Only way out is to kill client from task switcher and restart.
