That would be tricky since it is running on another machine. I will
try. I do believe someone else said that they could confirm the slow
behaviour with 6336 running locally as well. It may be that some X
drivers are slow at SDL_Flip and SDL_BlitSurface.
Hmm, my X server isn't compiled to allow tcp connections (only local
sockets), so avoiding ssh looks hard too.
Maybe Xvnc can do it. yeah Xvnc4 as an X server did the job, and I
vnc'd to it so qemu was running entirely locally on the machine with an
X connection. Works at normal speed.
So how does one fix this, since the change in 6336 makes it rather
painful for those where SDL_Flip and company are inefficient.
