Re: Tooltips problem on Gnome 3

[Fred Kiefer]

Thank you for the list. 
I just looked through the code in NSWindow that handles the expose events and 
we have no additional logging there.

From what I can see in the event list the posting of the expose event and the 
actual sending of he event to the window happen in the last two lines of the 
log. That is they follow immediately after one another. From this I don’t see 
why replacing the post with a send would result in a change. Or did you forget 
to undo your patch?

What you could try is to add —GNU-Debug=NSMotionEvent to also log mouse moved 
events.
