Make sure we only ask the spice local renderer for display updates in
|
|
case we have a valid primary surface. Without that spice is confused
|
|
and throws errors in case a display update request (triggered by
|
|
screendump for example) happens in parallel to a mode switch and hits
|
|
the race window where the old primary surface is gone and the new isn't
|
|
establisted yet.
