GLX Problems (sometimes)

[karrottop <karrottop@fuse.net>]

I have been having problems with GLX applications.  In some cases like
glxgears my glx system seems to be working just fine.  In other cases it
bombs out on me.  Here is an example with one of the really slick
screensavers.......

#######################################################################
karrottop@WeaponXbox:/usr/lib/xscreensaver$ ./rs-cyclone
X Error of failed request:  GLXBadRenderRequest
  Major opcode of failed request:  143 (GLX)
  Minor opcode of failed request:  1 (X_GLXRender)
  Serial number of failed request:  92
  Current serial number in output stream:  95

or trying to run eternal-lands......

#######################################################################
karrottop@WeaponXbox:~/eternal$ ./el.x86.linux.bin
X Error of failed request:  GLXBadRenderRequest
  Major opcode of failed request:  143 (GLX)
  Minor opcode of failed request:  1 (X_GLXRender)
  Serial number of failed request:  19
  Current serial number in output stream:  20

Any ideas?
