[Spice-devel] [spice-gtk PATCH] Handle single headed monitors that have a non-zero x, y config offset

[sstutsma at redhat.com]

From: Sandy Stutsman <sstutsma at redhat.com>

Each monitor on a Windows guest is represented as a separate, single-headed
device with its own framebuffer.  When there are multiple monitors, all
monitors but one will have a non-zero xy config position.  But even in
these cases the whole area (frame-buffer) of each monitor should be
updated.
