Suddenly, three diagonal lines consisting of dots (smaller than "." and
a few millimeters apart) appeared on my graphics monitor. I restarted
the DECwindows server, but that didn't help. The colour appears dark
against a bright background and light against a dark background, so
perhaps it is some shade of grey. On the other hand, it does some to be
either very dark or very light, one or the other appearing when the grey
background is only slightly different in its brightness. Also, they are
not visible at all in front of some colours (yellow, green, black).
Graphics card giving out?
