@carpet0928 Try it on a multiplayer server that has players in both realms, rather than local game.
Otherwise, I wrote a plugin to fix it for the server I'm playing on, so as not to wait a year for the next update.
It may turn out to be a launcher or library bug that got fixed, because it stopped happening while we still were in MC 1.8.1. I haven't experienced the problem in almost a month and I'm doing everything the same way that it used to freeze.
Freezes confirmed for 1.8.1. Using a multi-monitor set-up I often switch between MC and a browser and some times the game freezes. The game continues to run in there and renders everything when on a server, but it doesn't respond to clicking or anything.
In regular C Windows programming this happens when the window event callback function doesn't respond. I wouldn't know the Java interface for that, though.
After restarting the game, it no longer happens. I don't know what additional conditions there might be for it.
Sky light level 15 under roof is still a problem in 1.14.2 final release! My named zombies keep dying, and not even standing in water saves them.
