Subject: [PATCH] display: blank surface on creation
In theory, zero-ing the surface shouldn't be necessary, as only
invalidated/painted region should be shown. However, this results in
less artifacts on resolution changes (probably some regions are painted,
but with masks, blend, copy etc), in particular on console after VM
reboot.
