The problem is that modern desktops like to use colored cursors and the current Cirrus emulation only supports monochromatic cursors :-( Really no way around this without a special guest driver or new VGA emulation. On the other hand, I had toyed with a shared memory based display driver. That would give you more or less equivalent performance. However, I really don't think localhost VNC is that bad.
