[Bug 1371704] [NEW] flickering stripes/dashes screen corruption following recent update in 14.04

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

After a regular update of my LTS during the last week, the screen has
started showing  corruption. For instance, when I maximise a window, the
screen flickers for up to a second with an overlay of black dashes and
stripes, sometimes in a chevron pattern or just horizontal black dashes
covering the whole screen, especially on an external display.

It does not show up in a screen capture.
