Pushed by zamundaaa into branch 'master'. backends/drm: fall back to applying night light in non-linear space when linear fails While this isn't correct for gamma 2.2 with non-zero black level, it's close enough for most people, and it's definitely preferable for less capable hardware to have good performance over slightly more correct night light.

Created attachment 175849 [details] T4400_drm_info.txt After upgrading to Plasma 6.2, if I enable Night Light, the mouse movements become laggy, and animations are rendered slowly. This problem was not present at all in Plasma 6.1.
