Public bug reported:
Lenovo Thinkpad x200t
Ubuntu 15.04 AMD64
Since upgrade from 14.04 LTS is got following effect.
To reproduce: Open a program that scrolls graphical elements like firefox,
enter some web sites. Now scroll the content with mouse or keyboard up or down.
Result: Some colors from tiny elements smear about whole lines, visible chars
fades out. Scrolling has turned to a haunted house of flickering chars and
color expression. It was possible to take a screenshot, the yellow from tiny
left border smeared to the right like a leaked ink cartridge.
