Dotted square around entities

Does anybody already experienced this dotted square around entities? If yes, anyone got any way of making it disappear?

Sometimes it disappear and this “effect” happens more often in laptops screens and not so often in large displays …, but I really could find yet a pattern.

It happens in billboards with png, svg, etc.

Thank you very much!


We changed the size of the entity (a canvas) from 40 to 71, and now the square around it doesn’t appear.
