Almost like that...

...except I had I perfect rectangle at 0 degree rotation but on the left outside there was only one step in the line.

I would not care if it was a movie being played back - but when blanking some space for an external PIP that step is really annoying.

As I said I tried to reproduce the effect from the HUD GUI but there I always got the perfect and not steppy rectangle - so it might be a DMX issue.

I know that I will have steppiness with rotation - but when not rotating there should be a perfect shape without a step on one outside.
