  • In my understanding hdr is mostly supported in wayland (the core parts of it anyway) but it’s not finalised so it remains largely unimplemented. Kwin itself can only output hdr to the monitor but can’t get hdr video from programs due to a lack of vulkan support (?). There’s a patched vulkan layer to bridge the gap.

    I don’t think that’s the issue but I guess it could be. I’ll try an hdr brightness test video and compare it to the kwin managed sdr brightness slider to see

    Edit: Yup it works correctly

    Edit 2: I think the vulkan requirement might be just for it to work with hardware acceleration
