nxagent -- virtual screen X-server, older version
Don't think an actual "drivers" are in the picture here, just the screen
virtualizing X11 NX server.
Worked reasonably well with 5.5.5 and xrender=true. Epic disaster with
6.0.1. Six-oh-one with xrender=false seems a bit faster than 5.5.5 with
xrender=true, but not different enough to cause complaint. Does seem a
regression in the xrender code. Reading some of the above links it
appears xrender is a mixed proposition. Works brilliantly on many
targets, not-so-great on others. Could be a dumb bug that's imperceptible
on fast hardware.
