Hi.

Ok, it seems the screen-shot issue is deeper than the used frame-buffer  
type.
Is it 3D related thing? I mean is the screenshot correct when you are  
getting it with 3D turned off for the same VM?

About error warnings in terminal, you can ignore these warnings for now.
They are related to new functionality which is not yet implemented from  
the GUI side.
