Finally had an opportunity to do so, solution #3 worked. I didn't attempt #4, but that does not seem to be the issue either (as I put down, my version is 388.13 versus their 378.49 which seems to be the primary faulty driver version)
Attached.
Could you please provide a screenshot?
I just verified it. I put 8 coal into a furnace to smelt 64 cobblestone blocks and watched for the entire time. The coal burned at a rate of about ~102% +/- 0.5% that of the stone. I was present and had the furnace open the entire time. I could send you the server IP if you would like to personally reproduce it.
Possibly. However in other occasions when every chunk was loaded he whole time they still displayed issues.
Furthermore, both furnaces are on the same chunk, so I doubt that unloading the chunk would cause them to lag differently.
I used 8 coal to smelt 64 iron ore (in two different furnaces) - in one furnace, only 63 items were smelted. In the other, only 62, but the coal entirely consumed as if it had smelted 64.
confirmed for 1.12pre6
Unable to replicate, the command works fine for me. Given output (with chest filled with diamonds)
[11:47:44] The block at 65, 1, 2 had the data value of 3 (expected: 4)
Unable to reproduce. Are you sure the vine is a "source" vine block? The game could be registering it as a vine hanging off with no attached block, and as such being destroyed by anything destroying the vine above it. That might be a bug entirely of its own, however.
Have you recently installed/uninstalled a resource pack?
Unable to replicate, although my sneak key is R so that could be a potential cause.
I believe this is WAI, as snowballs are classified as projectiles (like arrows) which are supposed to destroy boats and the likes.
Apparently that's a bug of its own! ( MCL-5627 )
Well then, I'm not sure how to help you. Has the issue fixed itself yet?
If not, I might recommend deleting the playerdata (in .minecraft > saves > world) and recording what items are in your inventory and /giving yourself them.
did you click on "view crash report" ?
You need to hold the keys for 10 seconds and then release.
Yes it happens in singleplayer as well, I don't think a crash is going to help much as by the time the glitch occurs I can't interact with minecraft at all. Ignore the large numbers of entities, they're not the cause of the glitch.
