League of Legends (LoL) Question: blue circle at the right side of display screen above map (loading display

due to the fact a week i have a permanent blue circle on the proper side display screen above map. it happens handiest at some point of the loading display screen & in recreation. i have completely uninstalled league (additionally with ccleaner and eliminating the folders in c://) and reinstalled. nevertheless, this blue circle is there. also the hextech restore tool isn't always showing some thing suspicious. does every body understand this blue circle, or recognise how to resolve/put off it? thank you earlier!
