I fixed two things:
r6373) Partial updates only update the effected area, not the whole screen.
This effects both local and remote displays.
r6374) The virtual consoles coalesce multiple update regions into a single
region. This tends to effect both local and remote displays.
If reverting the second patch "fixes" your problem then the bug is probably
still latent. I just made the colsole code less dumb so that it doesn't
matter so much in practice.
