Subject: [PATCH] qxl: always update displaysurface on resize
Hans de Goede 5ba1a7
Hans de Goede 5ba1a7
Don't try to be clever and skip displaysurface reinitialization in case
Hans de Goede 5ba1a7
the size hasn't changed.  Other parameters might have changed
Hans de Goede 5ba1a7
nevertheless, for example depth or stride, resulting in rendering being
Hans de Goede 5ba1a7
broken then.
Hans de Goede 5ba1a7
Hans de Goede 5ba1a7
Trigger: boot linux guest with vesafb, start X11, make sure both vesafb
Hans de Goede 5ba1a7
and X11 use the display same resolution.  Then watch X11 screen being
Hans de Goede 5ba1a7
upside down.
