[Qemu-devel] vnc regression with -vga vmware

[Serge Hallyn]

Hi,

upstream git HEAD appears to have regressed with -vga vmware -vnc.

If I run 

        ./qemu-system-x86_64 -enable-kvm -vnc :1 -m 1024 -cdrom 
~/trusty-desktop-amd64.iso -vga vmware

then tightvncviewer gives me:

Connected to RFB server, using protocol version 3.8
No authentication needed
Authentication successful
Desktop name "QEMU"
VNC server default format:
32 bits per pixel.
Least significant byte first in each pixel.
True colour: max red 255 green 255 blue 255, shift red 16 green 8
blue 0
Using default colormap which is TrueColor.  Pixel format:
32 bits per pixel.
Least significant byte first in each pixel.
True colour: max red 255 green 255 blue 255, shift red 16
green 8 blue 0
Same machine: preferring raw encoding
Rect too large: 16x4 at (2352, 1766)

gvncviewer simply says 'Disconnected from server'.

It works fine if I don't use -vga vmware.

I bisected it to commit 12b316d: ui/vnc: optimize dirty bitmap tracking
