Out of curiosity I logged the events/receiver in MixxxApplication::notify and the last events after closing the main window were ``` Debug [Main]: Cleaning LibraryHashes/track_locations tables. Debug [Main]: SqlTransaction - Started...

Also, I tried to figure why Tango works while Mixxx crashes with the other skins: * removing spinnies and waveforms has no effect * creating only one VU meter per...

Another finding: neither ``` if (!isValid() || !isVisible()) { return; } ``` nor ``` auto* window = windowHandle(); if (window == nullptr || !window->isExposed() || !window->isVisible()) { return; } ```...

some more testing: The crash occurs even when creating the VU meter with the bare minimum (just a bare constructor, no other slots/event hooks, not hooked up to WaveformWidgetFactory) ```...

Thanks for testing. Yeah, probably related to the Qt version, though that doesn't help much since the 2.3 package for Ubuntu 20.04 is built with 5.12.8 So, if we stick...

Thanks for spending time for investigation! > might be related with the ControlProxy not being destroyed correctly... Not sure though. Don't think so. As I mentioned, the crash occurs also...

First of all, I wonder which situation is improved if the cover art is copied to the track directory? This branch just copies the cover image but still references the...

> @ronso0 When I understand you correct, you don't like that feature. Possible solutions: Oh, I'm not against this feature, thanks for your explanation. Now my only concern is to...
