SUMMARY I am using Kubuntu 25.10. But this bug is around for a while now. This is not critical, but is anoying. When right click on panel, going to show panel configuration and the choose Opaque instead Translucidy, after close the panel configuration dialog, the panel does not turn into opaque. Here's a video about it: https://www.youtube.com/watch?v=eXuufRK1_5E STEPS TO REPRODUCE 1. Kubuntu fully upgrade (09/26/2025) 2. Try to change the opacity of the panel, from translucidy to opaque. 3. OBSERVED RESULT Doesn´t keep the opaque option but get back to translucidy EXPECTED RESULT To keep opaque SOFTWARE/OS VERSIONS Operating System: Kubuntu 25.10 KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.17.0 Qt Version: 6.9.2 Kernel Version: 6.16.9-x64v3-xanmod1 (64-bit) Graphics Platform: X11 Processors: 12 × AMD Ryzen 5 5625U with Radeon Graphics Memory: 64 GiB of RAM (62.2 GiB usable) Graphics Processor: AMD Radeon Graphics Manufacturer: Positivo Bahia - VAIO Product Name: VJFE69F11X-B0411H ADDITIONAL INFORMATION
Thank you for the bug report, and the video that shows what's happening. I'm not able to reproduce this on Plasma built from git-master, or version 6.4.5 on Solus Can you reproduce this with a brand new user and the default panel?

It's seems a bug only related with Kubuntu. I already used VoidLinux and ParchLinux as well ArchLinux and Alpine, and there is no such bug.
If this is only present in Kubuntu, it may be due to something they have in their setup. If you can reproduce this with a brand new user, it's probably an old config file, conflicting with modern code. Otherwise it will be due to something Kubuntu is doing. This is something that should be reported to Kubuntu. See https://kubuntu.org/support/
