Scenario (Plasma 5.19.5 on Kubuntu 20.10): Starting with the default Kubuntu global theme, applying a new global theme with "Use desktop layout from theme" checked results in no wallpaper at all, just a black background. I can set individual wallpapers through Configure Desktop like normal, but any new activities or screens are black, with no wallpaper. From the new theme, if I select the default Kubuntu global theme with "Use desktop layout from theme" checked, the default theme will be restored along with the default wallpaper.
I have tried the following:
- Breeze, Breeze Dark, Ant-Dark and Nordic themes
- Upgraded Kubuntu/Plasma from 20.04/5.18.5 to 20.10/5.19.5
- Utilize Pling Store to install themes (themes install, but still no wallpaper)
I'm relatively new to Linux, so it's entirely possible I'm missing something obvious.
