Fusion
I frequently change visibility of items, select different components, etc. and suddenly get a canvas that looks like this. Clicking on the canvas fixes the issue and gets rid of the unwanted artifact.
Currently I am waiting for it to happen so that I can document exactly what steps immediately preceded the incorrect display. Trying to reproduce the above situation I used undo several times and then redo, but that did not recreate the issue. I decided to report the issue now in hopes that someone knows why it happens and if it on the list of Fusion issues to be fixed.
In many cases the light blue object shown is from a component in the design that has not been either active or visible for a very long time. During that time components have been created, components have been made active and edited, sketches have been edited etc. I have at times been working on a design and had the artifact from the same component appear over and over as I worked on newer components in the design.
I will add more information as I gather it.
