SUMMARY Changing the volume shows an applet in the middle of the screen which stays there for 1800 msec. The size of the icon is huge, the duration is too long and the location is wrong. Well, according to me. I know how to change it but with the next update the files I have changed are overwritten: /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/osd/Osd.qml and OsdItem.qml. Please put these settings somewhere in the /home/user/.config directory structure so they are not overwritten by a backup. Why isn't this a user setting? STEPS TO REPRODUCE 1. Change volume 2. 3. OBSERVED RESULT Huge applet which stays visible too long in the center of the screen EXPECTED RESULT A nice small applet somewhere in the corner which stays there as long as I want it visible, with a size that I like.

That's opinion, not a bug. As you have noticed you can change it, and there is a system for deploying it properly. Instead of modifying the files, copy the relevant folder into a new folder. Add a metadata.desktop to specify this as a new lnf which "inherits" from breeze. You'll get all the latest changes, but your OSD will remain the same.
