I don't think this new option will affect only when full-screen enabled, 
but probably it will affect also in a windowed mode. Perhaps you can 
just copy the description for DisplayGTK except the statement regarding 
virtio-gpu.

Also don't replace "Since: 7.0". It denotes the version that introduced 
the structure, not an individual member.

You don't need to assign false here. C initializes it as false by default.
