Short description of error
Hello. Following the tutorial from the link below, I noticed strange artifacts on the edges of the frame after rendering.

As you can see in the screenshot below, the artifacts are visible only after rendering (F12) - in the 3d window everything looks ok.
This situation only occurs when enabled.
