Description Bastien Nocera 2018-04-25 11:19:11 UTC 
WebKitWebProcess eats about 12 to 15% CPU when this site is opened, even when it is hidden: https://www.humblebundle.com/games/capcom-sega-psn

epiphany itself yo-yos between 5 and 12% CPU. The tab should be throttled down when hidden. Both processes' CPU usage drops to a couple of percent when that tab gets closed.

Can you move this to WebKit Bugzilla? This is way beyond the Epiphany level.

There actually is a PageThrottler nowadays, but it's fairly new and it sounds like it's not doing its job for whatever reason.

Thanks for taking the time to report this.
This issue is most likely a bug in WebKit. Please report the bug to https://bugs.webkit.org/ including a link to this bug report and noting the version of WebKitGTK+ that you have installed. When reporting the WebKit bug, be sure to include the prefix '[GTK]' in the bug summary and select the 'WebKit Gtk' component.
