Seems like it doesn't properly handle mouse events on Safari in macOS and only shows "frames with no pointer events". I assume it's because "pointerrawupdate" event is not supported there.

Also it's interesting that with ProMotion enabled it reports 16.67ms per frame (indicating 60Hz redraw rate) in Safari, but in Chrome it's 8.33.

Yes, I rely on pointerrawupdate. Thanks for letting me know! Unfortunately pointermove is typically synced with graphics in my limited experience, and I think I'd rather not show anything than provide wildly inaccurate numbers.

Although it's for gamepads, it's pretty much indispensable in debugging gamepad-related latency issues. For example, I found that my presumably 1000Hz controller can do only 500Hz in ideal conditions and it starts to drop at a much lower distance from the computer than advertised. Neat stuff.
