When using a non Breeze icon theme, Oxygen or Adwaita for example, there are a mix of the selected theme icons and Breeze icons; as shown in attached screenshot of the Application Menu. Although it is not restricted to that, I'm also seeing the effect in, for example Dolphin, where a lot of the mime type icons are the Breeze variants. Reproducible: Always Steps to Reproduce: 1. Use "System Settings -> Icons -> Theme" to select and apply a non Breeze Theme. 2. 3. Actual Results: The selected theme displays part Breeze icons. Expected Results: The selected theme does not display Breeze icons. System Settings: Version 5.4.3 KDE Frameworks 5.16.0 Qt 5.5.1 (built against 5.5.1) OS: Tumbleweed snapshot 20151124 note: this snapshot contained the kde-frameworks version update 5.15.0 -> 5.16.0 The Icons set I normally use is "Oxygen Ionised" (user theme located at ~/.local/share/icons) This is not restricted to that Icon set, "Oxygen" and "Adwaita" also exhibit this behaviour. It is not caused by missing Icons from the "Oxygen Ionised", "Oxygen" or "Adwaita" themes. Also, in the case of "Oxygen" variants the theme inherits "hicolor", not "Breeze". It is not a cache issue. Deleting "icon-cache.kcache" (from a VT whilst not logged in to KDE), does not "solve" the problem. It is not unique to a single user. Creating a new user (which initially has the default "Breeze" icon theme) and changing to "Oxygen" or "Adwaita" exhibits the same "mixed" theme. Prior to the kde-frameworks version update 5.15.0 -> 5.16.0 this problem did not exist.

Please for non-Breeze themes respect specifications: according http://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html , the default fallback icon theme must be "hicolor". I.e. as fallback, please use /usr/share/icons/hicolor/ and /usr/share/pixmaps

I have the same problem on openSUSE 42.1 with Plasma 5.5.4 when updated framework from 5.16.0 to 5.19.0. It was OK on 5.16.0 in my Plasma 5.5.4.

If you delete the corresponding breeze icon, the one from hicolor is taken then. It's "just" that "breeze" seems to be used as fallback additionally, and preferred over the real fallback, hicolor. But yes, still a bug (I suppose).
Please see this bug report: https://bugs.kde.org/show_bug.cgi?id=360664 for the reason behind this behaviour.
