OK, today I did more tests and I found some interesting information and
one solution for this problem. First apply the attached patch, this only
add some NSLog messages at NSWindow. Then run the test app with
--GNU-Debug=NSCursor. As you can see, sometimes when NSWindow
print the message "Mouse exited", NSCursor don't print the
corresponding message "mouseExited:". This is because there isn't a
cursor associated with that tracking rectangle. Even when, obviously,
there one cursor (the I-beam).

But obviously we should pop the current cursor. So one solution is write:

[[NSCursor currentCursor] mouseExited: theEvent];

when mouse exited (NSWindow line 4065). But I don't know if this can
cause problems.
