[0.9.2] Assembler graphic jitter

[Nemoder]

At the default(?) zoom level I am seeing a weird horizontal jitter on the level 1 assembler animation.

I see some jitter in roboport in zoom level 1 ( exactly 1 ).

I solved the left/right jitter of roboport on low-graphics settings on zoom 1, I guess it is the same problem as this, so I'm moving this to the resolved problems.
