My Mac II AppleColor Monitor did this (horizontally jumping) during
warmup, for a many minutes at a time.  There was a secret warranty to
have this fixed.  I took the machine in once, and they replaced the
analog board.  The problem temporarily disappeared.  Now the problem
lasts only a few seconds, about ten minutes into warmup, so I decided
to live with it.  After all, it is much better to have a 5 second
problem than a many-minute problem.
