Window mapped Images Bug?

Hi Blendheads o/

Problem Discription:
When the Texture Coordinates “Window” is enabled on a BG- Image (Plane (just diffuse)) I get an error…
Small lines ~1-5 px appiering on the left and bottom of the rendered image (also in Viewport). The lines also appiering when I disable DOF.

Example image (you must zoom into the image):


Can anybody confirm this error?
Is there a workaround? (The image has to have the “Window”- coordinates)

Best Regards
