Without commenting on any other part of this exciting console war, I don't know if this is true. Steam on my machine still always consumes nonzero CPU when minimized, possibly because it opens to the busy animation/video-filled front page then its WebView doesn't detect minimization. It's funny how Steam never comes up in the "stop making WebView/Electron apps" discussion when they were the original sinner (yes I know they were using IE originally).
