Created attachment 141475 [details] the nobs are both grayed out and semi-transparent SUMMARY muting a source or output sometimes greys out the nobs of unmuted sources/outputs STEPS TO REPRODUCE 1. have a source and an input in the volume applet (may also work with 2 outputs, couldn't test) 2. mute one and make sure the other is unmuted OBSERVED RESULT see attachment, both nobs are grayed out, can also see a small white line on the unnmuted slider, likely an artifact of the slider being both grayed out and not grayed out EXPECTED RESULT only the muted slider should be grayed out SOFTWARE/OS VERSIONS KDE Plasma Version: 5.22.5 KDE Frameworks Version: 5.85 Qt Version: 5.15.2 ADDITIONAL INFORMATION
aaaand just as I reported this there's an update: seems to happen at random as well, not only when some sliders are muted and others are not
well seems fixed with KF5.86
