From 0f68f8920573cdce1729a285a92ac8582df32841 Mon Sep 17 00:00:00 2001 From: Ulf Hermann Date: Tue, 27 Oct 2015 15:25:42 +0100 Subject: [PATCH] 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.
