Created attachment 120054 [details] gamut mask offset SUMMARY the new gamut mask feature looks great, but the the selectable area does not fit the visual part of the color wheel. The mask has an offset on the y-axis - It is possible to choose colors in the greyed out area above the mask, but it is not possible to choose colors above the lower end of the masked area. STEPS TO REPRODUCE choose a gamut mask and try to select colors near the borders of the mask in advanced color selector SOFTWARE/OS VERSIONS Krita 4.2.0 - alpha OSX High Sierra https://media.giphy.com/media/clFOfeoE7mfoYv9Syb/giphy.gif
