Description doncbugs 2021-10-09 05:34:01 UTC 
SUMMARY
Certain icons do not update when a theme is applied despite the theme containing the relevant icons. These icons are applied properly after replacing plasmashell. From the perspective of new users, this results in themes looking like an ugly, unfinished mishmash. Night Color Control is an example. The hamburger menus could also be considered one?

STEPS TO REPRODUCE
1. Have Night Color Control visible (I pinned Status and Notifications)
2. Enable the default theme (Breeze)
3. Apply a theme that has the icon for Night Color Control (I used Willow)

OBSERVED RESULT
Night Color Control does not change.

EXPECTED RESULT
Night Color should change with the other icons.

I have periodically seem this as well.

Are you seeing that it only affects System Tray icons, or other Plasma-themed icons elsewhere too?

While I haven't gone out of my way to test every single configuration, I know the sticky notes widget also has this issue. Since few themers will be looking through source code to see which icon is used where, it can be a bit difficult finding themes that contain the icons. The ChromeOS theme has [knotes.svg?], so you can view the icon not being changed in sticky notes until you replace plasmashell.

OK, thanks. That at least means it's not limited to just the System Tray, which means it's probably a broader issue, maybe with the ever-troublesome cache.
