  Description: examples/nxtext.  Artifacts when the pop-up window is opened.
               There are some artifacts that appear in the upper left hand
               corner.  These seems to be related to window creation.  At
               tiny artifact would not be surprising (the initial window
               should like at (0,0) and be of size (1,1)), but sometimes
               the artifact is larger.
  Status:      Open
