It appears that the general "Shape" properties are in the wrong place. Now they are placed under "PartDesign" properties but are used by all (probably) things that have "Shape". Part primitives, Draft planes, ImagePlane, ... Shouldn't those be moved to the General section of the settings?
I noticed that when creating an ImagePlane and the image had weird colors - Shape color is set to Random here. Image plane should set default white color.
