All transport belt sprite sheets can be aligned to one another, as they all share a common sequence of 8 frames to advance the belt one full position. If you watch the turbo transport belt, there is a slight stutter in the animation playback that is occasionally visible.

This is the offending issue:
Column 63 of 64 of the turbo transport belt spritesheet is misaligned for all rows.

Came here to 2nd this, i was working with them for the first time and i thought i was seeing things when i saw them jump every so often. Something doesn't line up for 1 frame and once you notice, it gets really annoying (try staring at a fully build but empty balancing belt setup for instance)

To further specify the bug that still exists in 2.0.28:
The 63rd frame in the turbo transport belt frame sequence is identical to the first frame in the frame sequence for all 20 directions. Therefore, a wrong frame was inserted for the 63rd frame.
