Description David G. 2023-02-08 12:55:31 UTC 
SUMMARY
When there is a maximized window (touching the bottom panel, for example), both the panel and the Application Launcher lose their transparency effect. They just become completely opaque. I don't understand what is causing this, or if it is possibly intended (although I don't know why it would be).


STEPS TO REPRODUCE
1. Launch KDE Plasma session (experienced on 5.26.5, still present on 5.26.90, both X11 and Wayland)
2. Maximize a window or make it touch a panel.

OBSERVED RESULT
Panel and Application Launcher immediately lose transparency effect.

EXPECTED RESULT
Panel and Application Launcher continue having a transparency effect.

SOFTWARE/OS VERSIONS
Linux: 6.1.9-arch1-1
KDE Plasma Version: 5.26.5/5.26.90
KDE Frameworks Version: 5.102.0
Qt Version: 5.15.8
Graphics platform: issue applies to both X11 and Wayland.

Yep, that's the intended behavior of the "Adaptive" opacity mode, which is the default setting. If you don't like this, you can set the opacity to "transparent" in the panel settings.
