[Audacity-devel] Spectrogram Cache

[Darrell W. <dar...@gm...>]

When scrubbing a spectrogram, the partial updates aren't working. More
precisely, WaveClip::
 GetSpectrogram() is failing to use the cache - copying over the previous
calculation that did not scroll out of view and only doing the new bit.

There were some commits around this code Oct 1.
