When placing/breaking blocks there is a short, but annoying lag spike
Notice the FPS in the screenshots below
System Specs:
A10 580k
8GB DDR3 RAM
HD 7950 (OC'd to 1 GHz)
Obviously my system should be able to handle minecraft at max settings easily.
To mods: Took 15 minutes looking through "lag" and "fps" search results for issues within 3 weeks ago

Edit: Added crash file
Unable to reproduce.
Hmm. Have you tried with half slabs?
It seems the lighting effects it. Look at the light level, and break half slabs in the block with that light level
when view distance is over 8 is when I get the lag
I'm having this bug while playing 14w11b, it started to happen when I updated my java.
