[Spice-devel] [PATCH 01/11] drm/qxl: Do not cause spice-server to clean our objects

[Frediano Ziglio]

If objects are moved back from system memory to VRAM (and spice id
created again) memory is already initialized so we need to set flag
to not clear memory.
If you don't do it after a while using desktop many images turns to
black or transparents.
