Platform Animations Shaking

I am working on a platformer and am using a rectangle sprite to do the pathing and pinning animations onto it. The pinned animations however vibrate or stutter when the player moves. Seems like it could be slight lag in updating the pin but I dont know. The capx I uploaded here,

dropbox.com/s/1a9bwxe69azt5b3/Animation%20Stuttering.capx

has everything except the movement disabled and i cannot for the life of me figure out how to fix it. I know that it is something i did wrong because sometime recently this started happening. Any help would be greatly appreciated! Thanks.

The problem is that you have the option Pixel Rounding set to ON. This forces your objects to be drawn at integer positions. Turn it OFF so objects can be drawn between pixels. The option is in the Project Settings window above the Window Size option.

Thanks a ton that was totally it!
