SUMMARY When "Dim inactive" desktop effect is used, KColoroChooser will pick inaccurate color unless it is minimized. KWin shortcut to minimize window do not apply on KColoroChooser when in pick color mode, nor does Alt+Tab. There is no shortcut to toggle "Dim inactive" effect either. While approaches to solve this could be various, the only workaround I have found is to use mouse gestures, the ones from Easystroke, to minimize the window, which ironically invoke a shortcut. STEPS TO REPRODUCE 1. Open KColoroChooser and engage "Pick screen color" 2. Try to minimize the window via shortcut OBSERVED RESULT Window will not minimize EXPECTED RESULT Window should minimize SOFTWARE/OS VERSIONS Manjaro
