Whenever I update or reinstall my GPU drivers, I click on Battle net and it shows up in my taskbar, but when i hover over it its a blank transparent screen. Restarting PC fixes this but still annoying. It only works if I use the system tray app to open a game or something.
Edit : The only way I got it to open is if I right clicked in task bar, and opened settings. Then it would be opened to system tray and opened normally. Seems like it only opens after being minimized to system tray.
