From 381600dad956ba246f8cb9806e70423f4121bae3 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 23 Jun 2014 10:35:22 +0100 Subject: [PATCH] ui/cocoa: Cope with first surface being same as initial window size Do the recalculation of the content dimensions in switchSurface if the current cdx is zero as well as if the new surface is a different size to the current window. This catches the case where the first surface registered happens to be 640x480 (our current window size), and fixes a bug where we would always display a black screen until the first surface of a different size was registered.
