Public bug reported:
I'm frequently seeing display artifacts in my daily use. One situation
where I commonly see them is scrolling on web pages, where they appear
as groups of thin lines that appear for a moment then go away. Another
place I see them is when the mouse pointer moves, where some of the
pixels remain at previous pointer locations briefly before disappearing.
I get the impression that these are related, as though some pixels from
screen lag in getting updated when something changes.
