--- Comment #3 from Zamundaaa <[email protected]> --- It's the wrong approach because apps use it for all sorts of bad ideas, from - doing night light without the required color management steps, making colors worse and inaccurate - applying custom "gamma" curves, again without taking color management into account - implementing brightness sliders in games (CS:GO did that, as a popular example, because SDL had (has?) an API for that) - applying custom "driver" options, like NVidia did Each and every one of these overwrites each other. In the X11 session, color management is completely unreliable because of that. You open the wrong settings page (KGamma), and just like that, your color calibration is gone. You open the Nvidia driver app, some game, same thing. Even output hotplugs mess it up on X11, because KWin and colord-kde race for adjusting night light and color calibration respectively... Iow, because of this API "decision" on Xorg, color management and night light both are completely unreliable there. That's to say nothing of HDR, which such an API just doesn't work for at all. -- You are receiving this mail because: You are watching all bug changes.
