Waveform shows spikes during silence - depending on zoom level

[Jürgen B]

In a project with imported wav file Cakewalk shows a spike in a silent section, depending on the zoom level.

Both attached screenshots show the same bars of the track. The difference is one zoom step (with Alt + mouse wheel). Further zooming shows and hides these spikes again, at different positions!

If this is of interest: The wav file was created by freezing a MIDI track in a different project. The rendered wav file was imported into a blank new project.

I did not experience this behavior so far, so I assume it is related to the latest update 2021.06.

So what is the issue other than visual?

[Jürgen B]

The problem is that I cannot trust the waveform anymore. If I see such a spike, I think that there is some click, pop, crackle, noise, whatever ... that I have to fix.

I have seen artifacts like this in the past, but your case may be a side-effect of the new waveform outlining feature. I've been noticing some added 'noise' in near-flatline audio that I think is related to this. You can try turning it off:  View > Display > Show Waveform Outlines.

I try to listen with my ears instead of my eyes.

Seems like glitchy cache stuff to me. Recompute image?

What I’d do just to make sure is open the audio in a wave editor. The big question is Cakewalk sometimes hiding details or is it being inaccurate in drawing the image.
