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. Paul
