Initially it looked like I could reproduce this problem but in fact I'm 
getting an error before the video gets encoded:

Spice-Warning **: red-parse-qxl.c:493:red_get_image: guest error: zero area bitmap


And indeed when I look at what qxl points to:

(gdb) p *((QXLImage *)0xa5986d0)
$1 = {descriptor = {id = 0, type = 0 '\000', flags = 0 '\000', width = 0, height = 0}, {
    bitmap = {format = 0 '\000', flags = 0 '\000', x = 0, y = 0, stride = 0, 
      palette = 173639440, data = 0}, quic = {data_size = 0, data = 0xa5986e6 ""}, 
    surface_image = {surface_id = 0}}}


This happens even without any of my patches obviously.
Do you know why I would be getting this?
