Ghosts

[TKI]

I have been doing a series of flying wing aircraft in plan layouts.

When I open files or save to file I see a sort of black "ghost" on top of some of the file icons, sort of like it has been marked up with a Sharpie after the fact.

They look like something that might have been drawn at one time but erased.

They only show up on the icon not on the working drawing nor on a JPG output.

I have attached a capture for reference.

Thanks,

Tim
