On the launcher, there’s a blue box that appears when I select anything, and it is constantly moving when there’s more options for it to go to, as if someone was holding down the tab button. It stops me from being able to scroll and see updates and news in the app, and is quite annoying. I have a video showing the problem as well if that could help
yea it seems to be an ongoing bug as of recent. theres another post of the same complaint from the beginning of the week. i have it myself.
SAME! This is driving me crazy. I can’t type in boxes or search for games because these blue boxes are constantly moving. I actually thought I had gotten some sort of malicious virus and reinstalled windows… twice 
And no reaction from Blizzard !!!
