Initial Comment:
So I am running using the VESA driver to run an Ubuntu 9.10 guest at
2560x1600 (I had to modify the xserver-video-vesa package to remove
an internal screen limit of 2048x2048 in the xorg vesa driver) and
everything works great except that the qemu vnc server appears to
clip at this resolution. The problem goes away if I run 1900x1200 and
it doesn't change if I run 16bit depth or 24bit depth.
I have attached two screenshots, the first is vncing directly into
qemu (which exhibits the problem) and the second is vncing to a vnc
server I have running in the guest which doesn't have the problem.
I poked around in vnc.c and couldn't see any limits but I feel like
its a buffer limit of some kind.
Also if you look very closely at the first image you can see that the
first row is drawn correctly all the way across but subsequent rows
are not.
If you need more information doesn't hesitate to ask.
Anthony, can you take a look at this? Seems like a serious issue,
could find nothing obvious in vnc.c.
