**System Information**
OSX 10.10.2. GTX 660ti
**Blender Version**
Broken: (example: 2.73.8 eacc3de)
Worked: (2.73a)
**Short description of error**
A scale node with scale of 1 will make image blurry, and shift pixels to the right.
**Exact steps for others to reproduce the error**
Open attached file and render it. The difference node reveals an outline. Seems the node is doing some filtering. But not only that, also pixels seem to blur not from the center, but towards the top and the right. You can see that in the transform node, if you mute and unmute you see how the image moves to the right a bit. This doesn't happen in 2.73a.
