I have been seeing a blue circle on the right side of the screen with an “N” through it every time I start up SC2. There is also a small triangle on the edge of the circle that follows my cursor like a compass needle. The circle remains on the screen through all the menus and during games. I have tried resetting the graphics and gameplay settings to default but it still remains. I’ve also tried the “scan and repair” option from the main battle.net menu and it still doesn’t disappear. I have screenshots of the circle here: imgur(dot)com/a/2b4jt4K - replace the (dot) with an actual one.
It sounds like the MSI Nahimic overlay. Does Ctrl+Shift+S get rid of it?
Yes, that did the trick, thanks!
