Public bug reported: Regularly the screen displays corruptions that change depending on disk i/o, keyboard/mouse and other system activity. The screen corruptions do not appear on each session and can be removed by selecting an alternative resolution and then changing back (or reverting without accepting the change).
The location of the corruptions is stereotypical and always has the same shape characteristics.
