Hi Hraban,
slightly modifying your MWE, I think I get what might fit your needs
(see below).
I never used \flushlayer and your sample shows that it doesn’t fit here.
The layer is relative to the page, not to the paper in this case.
And the state is an option for the layer (in \definelayer), not for the
background, being "start" its default value.
Just in case it might help,
Pablo
