I use krohnkite to arrange the windows automatically and it is essential to know which window the focus is on. Fortunately it is possible to do this in plasma by using the window borders and applying a highlight color for when they are in focus. However, this is not possible if the active theme is breeze-dark. As described in the readme of the krohnkite repository, this command will add the necessary settings ``` kwriteconfig5 --file ~/.config/kdeglobals --group WM --key frame 61,174,233 kwriteconfig5 --file ~/.config/kdeglobals --group WM --key inactiveFrame 239,240,241 ``` You can see this working if your chosen theme is not breeze-dark. In all the other color themes I applied, the border worked. ADDITIONAL INFORMATION Some people have reported this problem elsewhere and suggested that turning the current color theme off and on would fix the bug, but it didn't work. https://old.reddit.com/r/kde/comments/le120j/krohnkite_not_highlighting_active_windows_with/ https://old.reddit.com/r/kde/comments/lo6hj4/colored_window_borders_not_working_with_new_update/ https://github.com/esjeon/krohnkite/issues/148 https://github.com/esjeon/krohnkite/issues/129 https://github.com/esjeon/krohnkite/issues/68 SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.21.1 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 Kernel Version: 5.11.2-arch1-1 Graphics Platform: X11
This seems to be caused by the [Colors:Header] tag present in the new plasma 5.21 color schemes Any theme that does not have this will work as expected
Sorry this happened. In Plasma 5.21, when a color scheme has Header colors in it, these colors are ignored, and the Header colors are used to create a unified look for the window's entire header area. If you don't like this, you have three options: 1. Switch to a color scheme that does not have Header colors (e.g. the old Breeze color scheme, which is still shipped) 2. Remove the Header colors from your current color scheme 3. Create the desired appearance using the Header colors of your current color scheme, by adjusting the Normal/Inactive background colors in the Header section If you wish to use #2, I'm afraid the procedure is rather annoying since we were not able to write a GUI to remove header colors in time for 5.21. Sorry about that. To do this manually, you will need to save a copy of the color scheme, open it at ~/.local/share/color-schemes/[the color scheme] and remove the "Header" sections, then switch to another color scheme in the Colors KCM and back to your now-header-less custom color scheme.
