(In reply to Timothy Nikkel (:tnikkel) from comment #7) > Removing the VisualToLayout call in Event::GetScreenCoords results in a geckoview example that doesn't work: long tapping after zooming in doesn't highlight the expected word (or any word), and sending events to content doesn't seem to work as expected either (mouse move listeners don't get triggered for taps after zooming in). Althought the geckoview example I was testing in was broken the problem was pre-existing, and seems to be caused by something that landed after May 3, bug 1556556 is the obvious first candidate to look consider. I will file a new bug for this.
