Subject:   -52- 1.2 GLX Overlay text with GLX on 4.0.5
Date: 8 Apr 1994 00:00:01 EST

  In the sample programs (e.g. perfly) on some platforms, sometimes
  drawing messages (pfuDrawMessageCI) to the overlay planes in GLX mode
  doesn't work under 4.0.5.  Workaround: use only in GL mode (e.g. do
  not use "perfly -x") or upgrade to IRIX 5.2.
