- Sometimes the audio waveforms are not drawn
Been testing a lot of songs -- at least 50 individually and then 25 on subsequent tracks all at once and can find no failures where the waveform was not drawn (built from the latest GIT).
When the audio waveform is not drawn, have you done a "rebuilt index" to see if that fixes the problem?
Other than that, I have run out of ideas for a cause, but then I know you do things differently than I do so maybe that is pertinent to the problem? ...Phyllis
