A few days ago when I opened CS:GO I noticed that my AMD setting had been changed to Full Panel by itself somehow. I changed it back to Preserve Aspect Ratio and it worked just fine, the game showed 4:3 with black bars. Now it's happened again today and changing the setting back to Preserve Aspect Ratio has no effect, and the game stays stretched to Full Panel. I've used the clean wipe uninstaller and reinstalled the correct program/drivers and the problem persists. This is extremely frustrating because it ruins any muscle memory for the game. Any help fixing it is appreciated.
