SUMMARY For some reason, the "Volume feedback" option gets enabled sometimes for no apparent reason. I think, it happens on reboot, and not on every reboot but only sometimes. I don't know what triggers the problem. SOFTWARE/OS VERSIONS Kubuntu 18.10 KDE Plasma Version: 5.13.5 KDE Frameworks Version: 5.50.0 Qt Version: 5.11.1
Are you able to reproduce this in Plasma 5.17 or the upcoming 5.18?

I will not be able to test until the new plasma is released in Kubuntu.
In Kubuntu 19.10, this is not fixed: https://i.imgur.com/6zRo8dN.png I have both checkboxes for visual feedback unchecked, and I still cannot get rid of this huge volume dialog that blocks the video I'm watching while I'm adjusting the volume. If it would pop up on another monitor, that doesn't have focus, maybe I could stand it, but it always jumps in front of the picture of the youtube video I'm watching. Bad idea. This visual indicator needs to be localize to the small area of the system tray. However, the bug is the that the two checkboxes, in my screenshot above, do not prevent that dialog from taking over my screen like a boss.
This was just fixed in Plasma 5.19. Please re-test once it's released. Thanks!
