From 0f68f8920573cdce1729a285a92ac8582df32841 Mon Sep 17 00:00:00 2001

Subject: QtWidgets: Do hide/show via WA_OutsideWSRange for native widgets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If a native widget has a width or height of 0 we don't have to
invalidate its backing store as that is done by the window
system. Certain applications rely on ... interesting ... behavior
of certain window systems in this case.
Task-number: QTBUG-48321
