At extremly low resolution minecraft glitches

This ticket is invalid as it relates to a modded or 3rd party client/server.

• Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.

• Any plugin issues need to be addressed to the plugin creator.

• This site is for addressing issues related to the base unmodded MineCraft.

You used a modded Minecraft, though I can also reproduce under vanilla 1.5.1 pre-release.

Basically happens when vertical size is lower than 248px.
