SUMMARY Depending on your global day/night theme settings the wallpaper's counterpart doesn't work. STEPS TO REPRODUCE 1. Select Breeze Twilight as your light theme and Breeze Dark as your dark theme, configure Day/Night cycle, and let the themes switch accordingly. 2. Set your wallpaper to the Next wallpaper (or any wallpaper with a proper light and dark variant) 3. Set "Switch dynamic wallpapers" to 'Based on the day-night cycle' (which is the same cycle as for the theme) OBSERVED RESULT You get the wallpaper's dark variant 24/7, that is it doesn't switch between light and dark variant according to the day-night cycle. EXPECTED RESULT Well i would expect from my understanding that the wallpaper switches between light and dark variant based on the day-night cycle. However, the wallpaper just follows the plasma style, which for the Breeze Twilight happens to be Breez Dark (whereas the color scheme is set to Breeze Light). Now the wallpaper should follow its setting, and 'Based on whether the Plasma style is light or dark' happens to be a different setting. SOFTWARE/OS VERSIONS Operating System: Manjaro Linux KDE Plasma Version: 6.5.1 KDE Frameworks Version: 6.19.0 Qt Version: 6.10.0 Kernel Version: 6.12.56-1-MANJARO (64-bit) Graphics Platform: Wayland ADDITIONAL INFORMATION This might be related to https://bugs.kde.org/show_bug.cgi?id=511377 - somehow the "Switch dynamic wallpapers" settings don't seem to work well. Before 6.5 there wasn't such a setting and the wallpaper's variant was presumably chosen to follow the color scheme. Now although there are fine granular settings the wallpaper seemingly only follows the Plasma style in most cases.
The UI text is actually wrong; it claims it follows the color scheme, but in point of fact it follows the Plasma style. This will be corrected in Plasma 6.5.2. Thus, this is intentional, as with that configuration, the wallpaper follows the color of the Plasma theme, which in your setup is always dark.
> it claims it follows the color scheme, No this was in 6.5.0 and changed to plasma style in 6.5.1. The setting here reads 'Based on the day-night cycle'. As a side note maybe a good choice would be neither color scheme nor plasma style but following the themes the user chooses for light and dark?
Can you attach your ~/.config/plasma-org.kde.plasma.desktop-appletsrc to the bug report?
Created attachment 186370 [details] plasma-org.kde.plasma.desktop-appletsrc I removed the ScreenMapping - it's of no interest.
Sorry, I made a mistake - probably there was a confused state by using CLI and/or Plasma scripts like noted in https://bugs.kde.org/show_bug.cgi?id=511377 Anyway it works the wallpaper switches by day-night cycle (maybe just getting into an invalid state via CLI or scripts but this will probably investigated in https://bugs.kde.org/show_bug.cgi?id=511377)
