From 8046044514de3ef6a37bb982c8e239b9dc34208d Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Fri, 14 Sep 2012 22:09:23 +0200 Subject: [PATCH 225/228] qxl: always update displaysurface on resize Don't try to be clever and skip displaysurface reinitialization in case the size hasn't changed. Other parameters might have changed nevertheless, for example depth or stride, resulting in rendering being broken then. Trigger: boot linux guest with vesafb, start X11, make sure both vesafb and X11 use the display same resolution. Then watch X11 screen being upside down.
