when your holding shift, and swimming it shows the bottom of lake as a glitch every time you go up and down =/ and the game is VERY laggy im nevar horribley laggy but i go from 1 fps to around 20 =s
(ive always lagged in singleplayer quite a bit but this is wayyy more laggy) and in 1.7.3, i dont lagg in multiplayer at all)
The only bug i got is the block duplication glitch when in the crafting area and leaving extra items, that and creepers tend to stop and stand still when right in front of me on SSP like they do on very laggy SMP servers...
A bug that I had was after i would eat some food, it would show the animation but not give me any health. I tried it with porkchops and bread. I had to turn it to peaceful to get my health back. Also melon seeds and rotton flesh are invisable to me it just shows a number of how many i have in my inventory
The game seems to freeze at random times when trying to save, also there seems to be way too many non-aggressive animals. Found floating swamp trees with no land near. Water seems to change color at different times, at random, and blocks will become black and get no light to them at random.
so i generated a creative mode world and something weird generated, it was a giant tower of stone and dirt as if it was a chunk error, but it wasn't. and a lot of the world was messed up too. also, when you right click with a sword in your hand it does a weird animation that doesn't seem right. here is the link to a video of both issues.
Well... I found a bug, I'm not sure if it's been reported yet though. When you put down a red mushroom and use bonemeal on it, then the block the mushroom was placed on turns to dirt. It's kind of annoying if you were to place a diamond block under the mushroom, though.
