Two random thoughts about the MtxOrb driver:
- in the MtxOrb_clear() function the driver sets the backingstore 
  so that it always differs from framebuf
- the MtxOrb_flush() functio writes out one characer at a time.

These both may lead to the effects that Michelle is observing.

Things to test:
- remove the setting of the backingstore in MtxOrb_clear()
- try to find a more fficient implementation of the MtxOrb_flush()
  function [maybe the one from the CFontzPacket driver can
  work as a template]
