Still seems to be a problem on 1.6.2, certainly on multiplayer servers.

I've been grappling with this one too, without any success.

I've also tried both of the resource packs attached and have had no luck with either of them, though I can swap out any of the existing sounds.

Maybe we're missing some mcmeta files? Though I've had no luck finding any information on what their format would be. Near as I can tell it's not yet implemented.

Re: Texture animation definitions. I've checked the texture pack in question and for all of the textures that we have that are animated, those exist. No textures have shown up as missing, just corrupted.

The problem appears to be resolved in the 1.5.1 pre-release client for me however (still using a 1.5 server for now).

Update:
And now that I'm on 1.5.1 release client and server, it's back.

I am also having this problem in 1.5 on windows 7 64bit with 64bit Java 7.

The graphical issues seem to go away if you leave the area and come back, but doing so can be dangerous as you have no idea what any particular surface you want to walk over actually is. Switching texture packs seems to resolve the problem as well, possibly because it forces a reload of the pack.

Forcibly reloading the current pack with F3+T seems to resolve the glitch.

It's possibly worth noting that the modified textures are 32x32 and many are animated.

Apologies, the reason I didn't spot the other one as being the same issue is because the other indicates a crash and includes a null pointer exception error, no such events are visibly occurring in logs on my server. It merely disconnects the user with no useful information returned about why.
