Since updating to v3.6.0, the lighter inner band/boundary for the “inner handles” when using the Envelope tool or Multi-Tool is missing, so that audio tracks are all one color (except for the waveform). It’s the exact same problem described in this older thread, though in this case the inner band doesn’t appear or disappear whether or not the track is selected. I can’t find a view option to bring it back. Is this a bug, or a setting somewhere?
