[ROS2] Jerky controller on t0b1 during screen capture

[amalnanavati]

When running screen capture on t0b1 while moving the robot arm, the resulting controller motion is very jerky.

My hunch is that this is just due to high CPU utilization which is preventing the controller from running as fast as it should. I think the best solution is just to not run anything with high CPU utilization while commanding the robot. Nevertheless, I'm creating this issue in case folks notice jerky controller motions in other contexts as well.
