Anyone else seen this fade-in behaviour? The two clips were identical before I applied a fade-in to the first part of the first clip. It reduced the waveform of the whole clip. This is only a display problem. It sounds fine, and bouncing the clip fixes the problem. This doesn't happen in all projects.
 

Yea, that is weird. Does it happen on all tracks in that project or just that one?

I would maybe delete that track after moving all the clips to a new track and see if that fixes it. That track may be corrupted for some unknown reason.

I realised after sending this at something past midnight that i'd been here before. It's caused by tempo changes. The fade restarts at every tempo change. It's a known and acknowledged bug. Quite disconcerting in a project with lots of tempo changes.

Just for fun, try it. Open a new project, import a fragment of wav file, insert a tempo change halfway along, then add a fade in. You should get a fake fade at the tempo change.
