There is a visible delay when clicking any UI element in Opera, in addition to the UI only animating at 60 fps. In Chrome the delay is lower, but the UI still animates only at 60 fps. However the viewport is able to animate content up to the native refresh rate.
The UI in Safari, Edge, and Firefox all animate at the native refresh rate, with no click delay.
