Every time an app window changes all visible actors including the panel get repainted. But the panels mostly doesn't change, so should be cached via offscreen-redirect instead. [ Impact ] Ubuntu dock repaints the dock when a window changes [ Test case ] - Maximize a window - Change its content, by acting on it - Monitor gnome-shell CPU usage, and it should be lower than using previous dock version [ Possible regression ] The dock isn't repainted properly or it could produce artifacts in some scenarios To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1743976/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
