When items are in item frames around you they stay rendered no matter what causing fps lag.

Is this still an issue in 14w30c? If so, please update the "Affects Version/s" field. Otherwise, the bug will be marked as Fixed.
This bug appears to be solved in 1.8.1 pre-3.
Here's proof it works correctly in 1.8.1 pre-3:
The FPS is BAD when viewing item frames but good when looking the other way.

So this can be marked as solved.
I'm sorry for my previous post indicating otherwise.
*note that item models are very gpu-heavy to render compared to regular blocks or entities*
Seems to be fixed in 14w25b. The block continues to render, but there seems to be no unnatural FPS drop.
