SUMMARY Since 5.22 update many Plasma themes are broken. When using them the panel appears completely transparent (widgets and icons are visible, there is just no background color, blurry effect, etc) when they are actually translucent. It happens with many themes, some others work ok. Changing the opacity options doesn't improve this and set it to "opaque" only makes the panel completely opaque. I have been doing test and it seems it has to do with the file /widgets/panel-background.svg inside the theme folder STEPS TO REPRODUCE 1. Upgrade to Plasma 5.22 2. Use some translucent theme like https://store.kde.org/p/1002614/ (it happens with many others too) 3. Panel appears like if it was a transparent theme OBSERVED RESULT Panel appears like if it was a transparent theme EXPECTED RESULT The panel appears with the correct background and translucent effects SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Fedora 34 (available in About System) KDE Plasma Version: 5.22 KDE Frameworks Version: 5.82.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION
https://store.kde.org/p/1002614/ is not a Plasma theme, it's a Window decoration theme. However I found a Plasma theme of the same name: https://store.kde.org/p/998712/ I tried it on Plasma 5.22 and the theme appears to be working fine to me eye. So this far, I cannot reproduce the issue. Can you provide some examples of other themes that are broken for you, and also attach screenshots showing the broken appearance?
Yes, my mistake. I was intending the Plasma theme with the same name. It's curious, because if I start a new user and try that theme it seems to work properly. I'm going to do further tests and see what can I find.
