Hi - merging this in with an existing bug report for the underlying issue. Thanks! *** This bug has been marked as a duplicate of bug 501715 *** |
Created attachment 180678 [details] plasma-shell clock with forced RGB anti aliasing, resulting in colour-fringing SUMMARY At any UI-scale, except 100%!, various QML-written parts of KDE Plasma (shell, System Settings, KDE apps & third party Qt Quick apps such as Fedora Media Writer) exhibit forced RGB subpixel rendering, regardless of user-specified Subpixel setting. This is noticable on my BGR monitor as colour-fringing/chromatic abberation. I've had this issue for at least over a year (Sorry for not creating an issue earlier!). Reproducible on Fedora KDE, OpenSUSE TW, KDE Neon, Kubuntu. Plasma 5 doesn't have this issue. STEPS TO REPRODUCE 1. Set UI-scale over 100% 2. Adjust Subpixel Rendering (e.g. Off or BGR) and reboot OBSERVED RESULT Observe the fact that RGB subpixel rendering is still applied to plasma-shell, Discover & System Settings, etc. Causing colour-fringing/chromatic abberation on Non-RGB monitors, such as BGR or OLED monitors. EXPECTED RESULT Qt Quick QML parts & apps also acknowledging the user-specified subpixel font rendering setting. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora KDE, Kubuntu, KDE Neon, OpenSUSE TW KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.13 Qt Version: 6.9 ADDITIONAL INFORMATION I use a 4K TV with BGR subpixels at 200%. Plasma Wayland with amdgpu driver (RX 6800)
