[Spice-devel] [PATCH v10] Implementing WDDM interface to support multiple monitors and arbitrary resolution

   I managed to compile Windows 10 driver and try this patches.

When I resize the client screen (using either 1 or 2 QXL card) the screen keep
flickering. Did you notice the same issue?

The log is something like:
