Plasma-window-decorations VS kde-plasma-adaptive-wallpaper-accent-color

> That would take years. I use Debian Stable.

That kinda is the whole point of static releases like debian stable, ubuntu lts, red hat or windows ltsc? That you actively don't want to have any changes like these but want stable (=static) foundations to build on. (currently writing this on old stable; don't feel bothered to upgrade right now)

> I think Plasma has something like "Decorations" - can a custom decoration be used? Can one use scripts in the "Decorations"?

The software under discussion seems to be a change to the breeze window decoration so for this one probably not (yet), but e.g. for aurorae

https://store.kde.org/p/1678088

I've also tried other window decorations from KDE store, for example, No-Titlebar theme and Active Accent, but both of them makes the windows animations unbearable laggy.

Also. I don't know if it helps you, but there is ActiveAccentFrame. It put a color border around active windows. Can be installed from Get new thing for Windows Decoration in Settings.

The workaround I will be using is to change decorations from https://store.kde.org/p/1678088 to https://store.kde.org/p/1709569 So there is at least some sort of indication of active window :/

If you can't wait for it, you can use RealezzZ' and my Active Accent window decoration in the meantime: https://github.com/nclarius/Plasma-window-decorations

Frame: Without titlebar, for any color scheme

Active Accent window decoration - highlight the active window in accent color

As an alternative, there is also https://github.com/tantalising/kde-plasma-adaptive-wallpaper-accent-color

There is also a tool to automatically extract an accent color from the wallpaper and apply it: https://github.com/tantalising/kde-plasma-adaptive-wallpaper-accent-color One would just need to make sure to call it on activity switching.

It should update the color whenever the wallpaper changes. The message is probably because you still have some mixed up config. You can restart and then set any color scheme as default and then make sure you already have choosen a custom accent color in setting. After that start the app. The app is working fine in konsole for me. I have updated the readme. check this out. If you don't get accent for some wallpapers then it means either the wallpaper is changing so fast that it does not have enough time to change accent or it is generating a color close to previous accent that the new accent is almost indistinguishable. Sometimes the app fails to generate color when the image is not supported by qt. I am using qt and it sometimes for reason says the image is not valid. In that case I just skip that wallpaper instead of annoying user that the current wallpaper is broken.
