Hi all,

the new vnc code seems to be broken. At least all java based viewers
have serious problems, also realvnc for X

For example:

# kvm -cdrom ubuntu-9.04-desktop-amd64.iso -vnc :0 & vncviewer :0

CConn:       Throughput 20000 kbit/s - changing to hextile encoding
 CConn:       Throughput 20000 kbit/s - changing to full colour
 CConn:       Using pixel format depth 16 (16bpp) little-endian rgb565
 CConn:       Using hextile encoding
Rect too big: 10794x10794 at 10794,42 exceeds 720x400
 main:        Rect too big

The protocol stream seems to be clobbered somehow after the first
resize.

VNC Viewer Free Edition 4.1.1 for X - built Jan 30 2009 23:06:3

similar issues with tightvnc java viewer.

Any idea howto debug that further?


I think this is a known problem in qemu mentioned here on qemu-devel

http://article.gmane.org/gmane.comp.emulators.qemu/42321

The vinagre viewer seems to be a little more resilient. It's not a permanent solution of course if you need a java-based viewer.
