Bug Description

Surfaces that open underneath the cursor aren't aware the cursor is inside them until the cursor moves.

This means that a toolkit like GTK+ wont correctly render elements like buttons to indicate they are active.

This could be solved by getting a motion event with action=hover-enter after the surface is created.

The qtmir side fix is pretty easy though I'd like to wait until after port-event-2.0 lands to not create conflicts/more work.

I'm not sure yet of how to handle the Mir side fix.

I don't think this is very important. In fact I recall having seen such bugs on other desktops too. It's fairly common and does not affect usability in any significant way.
