Hi,
If a parent track is set to Prevent Sprectral Peaks performance options,
But Spectral peaks is activated for the other track,
Zooming and Dezooming (aka, refresh arrange view) make spectral peaks appears/disappears randomly on child tracks (even after peaks rebuild).
Expected behavior: parent track performance option shouldnt influence child tracks behavior.
I was able to reproduce in several projects. Win 10x64 REAPER v5.983 pre.
Best,
