I used qemu 2.1.2 and my command line: qemu-system-x86_64 \ -m 1024 \ -smp 1 \ -net none \ -enable-kvm \ -hda /home/lyj/qemu/tmp/xp_noqxl.append \ -device VGA,romfile=/root/qemu/seabios/out/vgabios.bin \ -spice port=5900,addr=0.0.0.0,disable-ticketing,seamless-migration=on \ -chardev stdio,id=debugcon \ -device isa-debugcon,iobase=0x0402,chardev=debugcon \
Do you still see the problem if spice is not enabled (that is, if you use the same command line without "-spice")?
If you do see corruption, we need to see the full debug log from the session.

Yes, I have tried gtk_monitor+VGA+seaVGABIOS.

I debugged both vgabios and qemu, and found the wbc didn't use vgabios interface but changing vgabios caused that the wbc run better. I found the wbc r/w vga register directly to set vga mode when added printf on vga_update_display in qemu. Uncomfortably, gfx_write_char have never been invoked and I deleted it in vgafb_write_char, that bring screen looking better. What happend? I can't understand.
Kevin, did you repeat screen mess?
Sorry for my poor level of English.
