Block Cracking Animation
When you face directly/straight down or up, the cracking animation/stages glitch's. This happens to me 90% of the time, and it is not a graphics card problem as it has been tried on multiple different cards.
What I expected to happen was...:
The cracking animation/stages to appear.
What actually happened was...:
Instead, the animation/stages either flicker or don't show at all.
Steps to Reproduce:
1. Stand on or below a block.
2. Face directly down or straight up.
3. Start breaking the block.
Environment
Windows 7 64bit, Latest java 64 bit

I couldn't reproduce the bug. It may be your graphic card.
I've had this bug even before the 1.4.2 updates. I've recently built a new PC.
I first had a laptop with a GeForce 330M card, now I'm just using Intel HD 4000 Integrated. Both have had the same problem.
This doesn't always happen for me but I was able to reproduce it. Same behavior occurs whilst looking directly up and more frequently in water (up or down). This bug has been around since beta.
