I tried several times to manually reproduce the issue with no luck: if
no vnc clients are supposed to be connected, how do you make the cirrus
emulated hw do a bitblit?
In any case it makes sense that the problem is in qemu_console_copy()
rather than in the rop function itself that only operates on the
emulated framebuffer.
But calling qemu_console_copy() in cirrus_do_copy() shouldn't be risky
because before that, we call vga_hw_update() that should do the resize.
Without a better understanding of the bug I will refrain from making any
suggestion.
