The issue is xorg returns a BadValue, should the capplet ignore them? How can it know than the call worked if xorg sent a BadValue? When the program gets a BadValue it assumes that the call has not worked. Setting as low priority, it could maybe made robust to xorg errors but most of the issue is due to xorg
