When I make changes in OpenStreetMap, I often need to extract the object colour from a picture or a video, as example for a building, bench or a roof. This collides with a feature in KDE which I really like: Dim Inactive Windows.
The setting is in the KDE settings, under Desktop Effects -> Dim Inactive. As the name implies, it dims (makes them a bit more dark) all non-active windows - which makes it visually clear which window is currently active. Quite useful.
For picking a colour from a picture/video I’m using
KColorChooser, which provides the colour in Hex code - exactly what I need in OSM.
KColorChooser is the active window, and all other windows are dimmed, it extracts the wrong colour from the picture/video - the colour which is already dimmed. Not what I need. Therefore when I do OSM edits, I temporarily disable this feature.
