Thanks for the bug report and the detailed troubleshooting! The developers will take a closer loko.
Indeed, thanks a lot for the helpful debugging! Are you using the default Breeze Plasma Style/color scheme, or any non-default ones?
i am using only the plasma and color theme from here: https://github.com/juxtopposed/Mystical-Blue-Theme/
Thanks. And does the issue happen with the default Breeze Global Theme?
upon Furter testing this only happens if the selected plasma theme does not have the little color wheel in the corner (including plasma light/dark)

Thanks a lot. Looks like it's Bug 503506. This bug report you opened is much better with the debugging, so I'm going to forward dupe that one to this one.
