The \'dance\' is used as screen saver to prevent burnin. It is very annoying.

Hmmm... I guess I\'ve not noticed that (burnin) as a problem. But, the screens
blank quickly if my attention moves to other things.

Burn-in goes back to when screens were cathode ray tubes, and leaving the beam on the phosphor for too long got ti hot enough to change it.

My last cathode rate screen got retired about 15 years ago.

Finding desk space for it had become a problem.

Burn-in is back as a problem with some (older) OLED screens. It remains
to be seen whether the advertised fixes work in the longer term.

LCD displays were pretty much immune to it.
