Summary: The feature has always been considered experimental. Unfortunately it is completely unmaintained and hasn't seen any commits in years. It requires kolor-manager to function, but that has not seen a release based on frameworks yet. This makes it difficult to maintain. In fact I have never been able from the introduction till now to setup a color corrected system. One needs kolor-manager and oyranos and especially the latter is hardly available on any linux distribution (e.g. not on the Debian/Ubuntu systems). Due to being unmaintained color correction in KWin did not keep up with recent changes. Neither did it see any updates during the xlib->xcb port, nor during the Wayland port. Especially the Wayland port with the rendering changes make it unlikely to function correctly. E.g. Wayland introduced a proper per-screen rendering, while color correction did a "fake" per screen rendering. How that is going to work in combination is something nobody ever tried. Now after the introduction of proper per-screen rendering the solution would be to port color correction to the new api, but that never happened. Color correction also modified the shaders, but a newer shader API got introduced some time ago. Whether the color correction shader support that or not, is unknown to me. Also which shader language versions are supported. I know it was based on 3d texture support, which back on introduction was partially lacking in OpenGL ES. Nowadays that changed, but color correction didn't update. Last but not least it is completely X11 based and there is no work on how to make it work with Wayland. Given all the problems, especially the fact that it is unmaintained and cannot be setup on my system, means to me that the only solution is to remove it. I'm open to having it reintroduced in future, but only if the availability on Linux distributions gets addressed before. As long as major linux distributions do not ship this feature, it should not be in KWin. Given that I must say that it was a mistake to add it in the first place and I need to point out that I was against the merge back then.

you can reset this protection but be aware that this might result in an immediate crash!

Alternatively, you might want to use the XRender backend instead.</string>
