- workaround for clearing the start screen in Vulkan.

Browse source 
There seems to be a bug in the backend, but I have no idea what's wrong.
Clearing the start screen with a ClearRect call renders the 2D drawer in an unstable state. So for now, clear the screen by rendering a texture, but with light color black, which produces the same effect without later breaking stuff.
