This issue happens in Editor Component => Font & Color Schemas. If I'm using a color scheme of my choice and then accidentally click on Use KDE Color Scheme button, it will automatically overwrite the color scheme I was using. I tried this on all preinstalled color schemes and they all turned into my default KDE Color Scheme. This can be annoying when testing color schemes. KDE Plasma Version: 5.14.5 KDE Frameworks Version: 5.54.0 Qt Version: 5.11.3
This will be resolved once KTextEditor switches to using the Themes from the KSyntaxHighlighting framework. Details are tracked here: https://phabricator.kde.org/T4054 https://phabricator.kde.org/T3973
