From 7d270b1c21c692478245b90bfac0aa54c6a8d98a Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 24 Dec 2013 02:51:47 +0000 Subject: [PATCH] ui/cocoa: Draw black rectangle if we have no data yet If our redraw method is called before we have any data from the guest, then draw a black rectangle rather than leaving the window empty. This mostly only matters when the guest machine has no framebuffer device, but it is more in line with the behaviour of other QEMU UIs.
