Bumping my own post. Since I pay close attention to my GPU's temperature I'm bringing this issue forward and simply requesting more people to try it so that cause of this can be determined. It's very easy to reproduce by the way. Just use a resource temperature sensor software (like Open Hardware Monitor) and simply compare the idle temperatures with "Change Location" screen remain open and closed. I've posted screenshots below: Please help me identify the cause here since only f.lux shows this weird behavior. I would like to know whether if only I'm having this problem or not.
