- Can you paste your qemu command line so we can know for sure you have
  streaming enabled? e.g [0].

- Can you paste your client's debug log with --spice-debug?
  e.g ./spicy --spice-debug ?

If you are using gstreamer, you should see a lot of the following:
(...)
(spicy:14506): GSpice-DEBUG: channel-display.c:1499 display-2:0: video latency: 391
(spicy:14506): GSpice-DEBUG: channel-display.c:1499 display-2:0: video latency: 387
(spicy:14506): GSpice-DEBUG: channel-display.c:1499 display-2:0: video latency: 387
(spicy:14506): GSpice-DEBUG: channel-display.c:1499 display-2:0: video latency: 390
(spicy:14506): GSpice-DEBUG: channel-display.c:1499 display-2:0: video latency: 386
(spicy:14506): GSpice-DEBUG: channel-display.c:1499 display-2:0: video latency: 389
(spicy:14506): GSpice-DEBUG: channel-display.c:1499 display-2:0: video latency: 389
(...)

[0] It should contain streaming-video...
-spice port=5900,addr=127.0.0.1,disable-ticketing,
       image-compression=off,streaming-video=all,
       seamless-migration=on

I've built my spice-gtk with --disable-builtin-mjpeg so it uses
GStreamer even with mjpeg streams.

Cheers,
    toso
