I remember something like this in regards to GLCanvas,
ie we try to remove the 'background erase', which may not work all the time
on different platforms.

Please follow proper bug reporting:
  http://jogamp.org/wiki/index.php/Jogl_FAQ#Bugreports_.26_Testing

Please read the 'junit test' part carefully, since that guarantees we quickly
can verify this. Sure we need the other information as well.

So I guess, this will become the 'Flickering GLCanvas' bug.
NEWT works fine I assume.

Thank you.
