KDE Plasma 5.22 Will Feature Adaptive Transparency
The KDE Plasma desktop will have three new opacity settings for the panels starting with the upcoming 5.22 release: Adaptive, Opaque and Translucent.
The next KDE release will have a three transparency options: Adaptive, Opaque and Translucent. The new
Adaptive will make the panel
Opaque only when a window is maximized and transparent when there are no maximized windows.
Theme authors can add a new
Opaque option for configuring the new functionality by adding
to some "meta-data file". Nobody from the KDE project where able to clarify which specific theme-file this would be.
Selective transparency is on by default for all users unless the active theme overrides it.
The new panel transparency settings may be specially as an alternative to KDE Plasma users who would like to automatically hide their panels since that feature has been broken, and specially broken when the KDE window manager kwin is configured with
HideUtilityWindowsForInactive=false, several decades.
