Subject: [PATCH] qxl: always update displaysurface on resize
|
2012-09-25 19:47:24 +00:00
|
|
|
|
|
|
|
|
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.
