I don't understand, either, especially since I don't see this on w32.

The recipes in bug#18757 seem to indicate that redisplaying the
frame's title, due to the change in the selected buffer, causes the
flickering.  That flickering started happening with the upgrade to
version 10.10 of the OS, so perhaps it's no linger an issue with the
current OS versions?

Do you still see the flicker if you revert the above commit?
