Onscreen artifacts

What is this onscreen madness going on when I attempt to scallop a rectangle?

Sad

  • Looks like you are trying to scallop a rectangle whose corners are already scalloped.  The onscreen preview is showing what will happen when you do this (if you hit apply, this is the result).

    If you're trying to make a rectangle with scalloped corners, simply create a new rectangle, then change the corner type to scalloped (rectangle tool toolbar), then adjust the radius via the rectangle tool toolbar.  The FSC docker is a destructive operation, meaning that if you apply this to a rectangle, the result is a curve.
