I originally installed Leap 15.3 with KDE Plasma. Then I installed GNOME too. When I use a GNOME session many of the menu/app icons are missing. Replaced with a generic icon or missing all together. The drop down menu is missing the little gear icon too. I went into GNOME settings and changed the icon theme to Adwaita but it didn't help. I also created a new user account and tried logging in but the icons were still wrong.

Can it be fixed?
