Hi. I wish to create a visible waveform from some audio tracks, but the audio waveform filter does not create the waveform. Changing the colour and thickness of the non-visible line changes nothing. Is there something I'm doing wrong, or is this a bug?

I can confirm, is not working, can you fill an issue report? https://invent.kde.org/kde/kdenlive/issues (place the image as a PNG) thank you!
