That's as may be true.  But the leap from "it's worse" to "because it
supports so many devices" is just nonsense.

That's really a property of the server.  Every resize is an allocate /
copy / free cycle when compositing.  Which is then made worse because
the app inevitably ends up repainting the whole thing, so the copy was a
waste of time.

A modest amount of hysteresis on window sizing would go a long way here.
