Apologies. The "Parent Frame" and "Child Frame" are labelled backwards in my previous post. Actually, just loading the files locally shows a cap of 30fps for the frame in the iOS Simulator. Created attachment 405684 [details]
Test
Attached the sample from the bug description as a ZIP archive, opening the 213344-parent.html shows the issue where the stats are capped at 30fps.
Cc'ing Simon, who wrote the patch in question (r215070). If I add a "pointerup" event listener in the child document, the 30fps throttle is released if I tap in the document. However, if I do a different kind of gesture which does not yield a simulated "click", the 30fps remains in place. |
