+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.
