Public bug reported:
On Intrepid Ibex and Jaunty Jackalope when resuming after Suspend there
seems to be a timing problem in the display driver that causes the
display to jitter horizontally whenever there is main processor
intensive activity. Amount of jitter depends upon activity running from
a few pixels up to 1/3rd of the screen width. The system becomes only
marginally usable among other reasons because it is hard to mouse click
on widgets that are small compared to the amount of jitter.
