Logic Studio apps On screen controls move on their own


Recently MainStage 3.3.2 has started exhibiting some very odd behaviour. When I move a controller, the Logic style mixing controls (like faders and sends) which are linked to the controller move as expected. However the MainStage graphic onscreen knobs do not follow the same movments as the Logic mixer. The graphic controls continue to move on their own up and down for some time after the controller has stopped sending a signal. This strange animation does not affect the actual paramiters these graphic knobs and faders are connected to on the Logic mixer. It appers to be some sort of bug.

Has anyone seen this behaviour? I've not seen it before the update and I've been using MainStage regularly since version 1.
