It seems this problem is mostly gone.  I'm not sure when the improvements
happened.

The only time I see left over artifacts is when I use the tool buttons to open
dialogs and then move the dialogs.  Only the artifacts from the first few
frames remain, whereas when this bug was originally reported, artifacts always
remained.

If I use the menus to open dialogs, I don't see this problem.  So perhaps the
menus going away causes extra repaints, which in turn prevent artifacts from
showing up.
