When using Shuffleboard, the OpenJDK binary consumes a lot of cpu. After starting the DS and having the Shuffleboard loaded, the cpu consumption is high, but things seem to function acceptably.
However, if we close the lid on the DS laptop and then later open it back up, the cpu consumption of OpenJDK binary is even higher to the point the DS PC is unusable. This does not happen with every close and open of the lid but most of the time. When this occurs, we have to kill the shuffleboard and reload and it works until next lid close.
