Big Gray Golem

Confirmed since 1.4.x. Last update fixed the visual glitching, but the audio and related lag spikes are still present.

This is NOT solely a Bukkit problem. I am experiencing the same thing using Single Player Survival mode, and it appears to be related to 1.4.x's relationship with OptiFine. The OF developer cannot figure out the problem, and insists it is a MC core problem.

I am only experiencing the "Unable to Locate Sign" problem (which erases sign text)... no other chunk errors that I notice.

Unfortuntely, this bug is polluted with multiple issues, and all other "minecart clipping" threads are being closed as duplicates of this one. I am just writing to confirm the minecart clipping/jerking problem, which occurs along with corrupted audio playback of the minecart sound effects. I hope others will open another bug on the falling entities problem, or Mojang will split this. The minecart lag problem is severe. Tested in new worlds, as well as heavily populated ones. Tested using multiple RAM allotments, different audio drivers, video drivers. No effect. The visible stutter of the cart occurs in all views (1st and 3rd person), and occurs 100% of the time. The related audio stutter is intermittent.
