Hi Max, I'll take a look at your issue #1 .

Your issue #2 as far as I know is just standard Mac behavior. I agree that it's weird but there is a longstanding Mac behavior that mouse events are only sent to the active window, but with an exception for scroll events apparently.

You should be able to reproduce it with most Mac applications. For example launch Safari and size the window a little small so there are scroll bars. Click in the Safari window so it's the key window. Note that you can pinch to zoom and scroll. Now click on the desktop so Safari is not active. Move the mouse cursor over the Safari window without clicking and note that you can't pinch to zoom but you can do scroll gestures.

Maybe there's some way that I can get it to work, but that's the default behavior.
