Often when I'm moving around on the map, new chunks will not load before entering them. Even after attempting to move into a new chunk, it still appears as empty space, often showing underground caves before loading the actual ground I should be standing on. This has happened in previous versions, but it happens far more often now and it's significantly worse.

I don't have any steps to reproduce the bug; it happens almost constantly and it's impossible to avoid. Happens on all world types, including superflat (although with superflat it's not as bad)

If there's something painfully obvious I'm missing or I've made some stupid mistake, let me know. I'm using a high-end gaming desktop, so I know it's not the computer itself. Maybe I can update Java? I've included some screenshots.
