Comment 7 for bug 1086999

For me this is a 1.11.0 blocker because every new user will try at least waveform scratch and hitting this bug will lead to a bad first impression.

I looks like, it can be solved by tweaking the PID controller for different latency's.
Currently I have not managed to find a parameter set that is suitable for low and high latencies.

I am not sure yet if there is no underlying issue, but for 1.11.0 we should at least get rid of the oscillation with any latancy at cost of responsiveness

@RJ: Do you have own test results for different PID setting?
