I also saw this behaviour on my Onyx RE2. It vanished
when i upgraded from Performer 2.04 / Performer 2.1 to
Performer 2.2. It happened at unpredictable times and
neither the vulcan death grip, killing the x display
manager via kill, or using stopgfx and startgfx had any
effect whatsoever. The only solution i could find was
to reboot...
