Zwift background app keeps GPU awake

Just for info - the new version of Zwift (and the associated background app) keeps the dedicated GPU awake on my laptop which has quite a big impact on battery life. It looks like it’s the webview used for the login page, which should be closed when Zwift exits, but isn’t in this case.

Right clicking on the Zwift taskbar icon and choosing quit solves the problem, but obviously loses the benefits of automatic updates.
