CustomNameVisible doesn't work in 34b, using this command:
/summon Villager ~ ~ ~ {Profession:4,Career:1,CustomName:Bill,CustomNameVisible:1}
I punched a NoAI Enderman in the face and he teleported away and back.
Still occurs in 14w10c.
Fill it to the brim.
/setblock ~-1 ~ ~ air
Still in 14w08a v.2, and much worse. I got teleported over 30 blocks.
EDIT: It doesn't happen all the time
Confirmed in 08a with the baby pigmen.
Also occurs when the underwater.png file is invisible.
Also occurs on beacon beams
Also occurs when on fire
Confirmed in 08a. Also when it rained the sun was black.
Assuming that's due to the chest being a tile entity
This also occurs in PE on an iOS 7.0.6 iPad 2 with 16GB of memory. Should I create a separate bug report for that?
Also occurs with maps, required to sneak to see the lower left corner due to the new fancy way of holding maps (which I love and I hope the old way of holding maps never comes back)
Confirmed for the shaders.
Is this in w08a?
This occurred even in 1.6.2. This is because item frames and paintings are considered entities by the game, and not blocks, so mobGriefing wouldn't effect them.
Have you tried the latest snapshot?
"Maybe try a lowerresolution resourcepack?" Go into your options.txt and remove the resource pack name. That may help.
Still occurs in 14w34b.
