So this was happening for a while. I didnt notice any visible reason which would started it. But i noticed that this happens everytime some taskbar-window(above clock in windows) pop-ups like ICQ messages/status or skype status my sensitivity increases to 100(i am using 4000 DPI and sensitivity 2 now) Also it happens sometimes without any visible reason. I am using roccat kone.
Any help is apprecieted cause its a bit annoying
