Has anyone else had the issue of paths "sticking" on the screen too long, leaving your display dirty?  As in this:

You program line 15 and move on.  As your programming line 16 and beyond, the green path lines and red transition points from line 15 just sit there and never go away.  In this shot, I've got the operation open that checks the yellow circle, but you can see all the pathing garbage from the front end of the part.

This will generally go away if I close the program and re-open, but it happens all the time.  Is it just me?
