Ever wondered why websites and web applications keep consuming CPU/power in the background with #GNOMEWeb?
This is the #WebKitGTK enhancement request I have filed to allow stopping the animations frame clock and telling websites that the window is not in focus (so that they can throttle themselves): https://bugs.webkit.org/show_bug.cgi?id=285167
Not sure how widespread power throttling is among #web apps, but this provides a path for pretty significant power savings in #GNOME, #LinuxMobile & #embedded with #Wayland.
