Two days ago I’ve installed EndeavourOS KDE/plasma (6.5.5) on a AMD radeon RX 6650 XT system.
In applications as LibreOffice and Inkscape the font color is not adapted on the screen if I change it. In old documents with different font colors, all fonts are shown black. I’t doesn’t change if I choose an other global theme.
On this system with the most recent KDE Gear release (25.12.1) and Wayland (no X11) – not the default Leap 16.0 KDE Plasma versions – I’m not seeing the issues you’re experiencing.
Thank you for your welcome and your reply. I see you also use a AMD graphical card and processor. Before I used Manjaro and there there were no problems. So It must be something in the settings. But I didn’t change mutch in the defaut settings…
