Weird on/off AU issue Logic - with juce demo plugin

current development branch

if i turn off a juce-plugin on the master track, i sometimes hear a short sound which actually comes from a muted track in logic.

My first thought this is a logic issue, but, it seems only Juce-Plugins are affected.

My assumption that the AU-Wrapper has maybe a bug, that the audio-block is not always overwritten properly.

Its a little bit difficult to reproduce the behavior, i couldn’t find reliable way (so this speaks for the theory that a random audio block is not overwritten properly)

Where there recently changes in the AU-Wrapper which may cause this issue/bug?
