** Description changed: gnome-shell is wasting CPU repainting an unchanging panel and dock. 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
