SUMMARY If HDR is enabled, as the screen is lowered panel and plasmoid backgrounds get lighter and lighter, in the end the as light as the foreground. The brightness is the same as the rest. When taking a screenshot, it doesn't show. I tried adjusting min/max HDR brightness but didn't have an effect STEPS TO REPRODUCE 1. Enable HDR 2. Lower screen brightness Output: 1 eDP-1 efd88d26-5b49-422a-b003-6a751b915f08 enabled connected priority 2 Panel replication source:0 Modes: 1:2560x1600@165.00*! 2:2560x1600@60.00 Geometry: 1920,13 1707x1067 Scale: 1.5 Rotation: 1 Overscan: 0 Vrr: Automatic RgbRange: unknown HDR: enabled SDR brightness: 930 nits SDR gamut wideness: 90% Peak brightness: 1450 nits, overridden with: 1450 nits Max average brightness: 508 nits Min brightness: 0.0006 nits Wide Color Gamut: enabled ICC profile: none Color profile source: EDID Color power preference: prefer efficiency and performance Brightness control: supported, set to 32% and dimming to 100% Color resolution: unknown Allow EDR: always Sharpness control: unsupported SOFTWARE/OS VERSIONS Operating System: Fedora Linux 43 KDE Plasma Version: 6.5.5 KDE Frameworks Version: 6.22.0 Qt Version: 6.10.1 Kernel Version: 6.18.9-200.fc43.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 260 w/ Radeon 780M Graphics Graphics Processor 1: NVIDIA GeForce RTX 5060 Laptop GPU Graphics Processor 2: AMD Radeon 780M Graphics Manufacturer: LENOVO
