SUMMARY STEPS TO REPRODUCE 1. Try to pick a color from the screen with anything that uses the color picker effect (like the plasma color picker widget or a color chooser in an app, for example spectacle editing tools) OBSERVED RESULT It picks a color with brightness 0 and wrong hue and saturation values, resulting on #000000 hex color EXPECTED RESULT It should pick the selected color below the mouse pointer SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.90.0 KDE Frameworks Version: 5.246.0 Qt Version: 6.6.1 Kernel Version: 6.1.64-1-lts (64-bit) Graphics Platform: Wayland ADDITIONAL INFORMATION Maybe a separated bug unrelated to kwin but the pick color button doesn't show up in the kcolorchooser app, but does show up on apps that have a color picker
