What GPU hardware are you using on this system? Integeated Intel GPU. Iirc it worked correctly with Plasma 5. It's not broken on Wayland. Does it start working again if you run kwin_x11 --replace? Or simply turning night light off and then on again? Both restarting KWin and toggling night light makes it work again. Okay, then you probably have colord or similar running, which sets the gamma ramp on display hotplug events, and overrides the gamma ramps set by KWin. This isn't really possible to fix on Xorg, because there's no way for KWin to get exclusive control over the color management hardware. Yes, disabling colord fixes it. |
