Non-RealTime Performer when using X-windows

Hello:

I am running on a 4-CPU Oynx. I have separate app, cull, draw, and isect processes. The app, cull and draw processes
are running at non-degrading real-time priorities, locked into cpu 1, 2, and 3 respectively. Those CPUs are
restricted, isolated, and non-preemptive.

I have a 480x480 performer window. I have another background task supporting a GUI x-window. My Performer tasks run
perfectly without any glitch when there is no x-window activity. However, when I make GL calls in my background task,
or move the mouse causing different windows to become active, the Performer tasks slip frames causing a jerky image.
Can anyone explain what's going on?
