GPU usage with open Battle.net

When Battle.net is open, it eats up to 70% of my GPU when idle (per task manager). This does go away when I minimize Battle.net, but it makes it very annoying to use the app as my fans go full blast and my laptop starts heating up. It makes no sense to me why a simple desktop application would eat as much GPU resources as a AAA game. I don’t have this problem with Steam or Origin.

Disabling hardware acceleration in the settings did not change anything. Is there a way to actually disable GPU usage?
