  Hi,

> Any other ideas as to how to eliminate that Blit cleanly?

Well, "cleanly" pretty much implies "supported by toolkit".

gtk glarea for example sets up a framebuffer and expects the application
render to that framebuffer.  So qemu glarea code does a fb-to-fb blit.

Other reasons are scaling and cursor rendering.  Not all reasons apply
to all UIs.  I think when using spice qemu doesn't blit (not fully sure
what happens inside spice-server), but it could very well be that the
spice-client does the blit instead, i.e. we just shift the issue to
another place ...

take care,
  Gerd
