Dash: when using static blur, opening the Dash over windows that change, those windows flash thru

[Doug McMahon]

There's quite a nimber that will cause this but most obvious is Totem
Test case:
enable static blur, open Dash to set
Open any audio or video file in Totem so it will be under Dash area
Open the Dash, totem will continually flash thru

Also affects Unity 5.16.0 in precise. See screenshoot

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

As a matter of fact, also the alt+tab switcher gets painted over by any stuff happening in the background...

I think it's possible the fix for bug 1070735 in Unity 6.12 might solve this. Not sure when that will be released to quantal.

With unity_6.12.0-0ubuntu4 in raring the effect is still noticed unless
the 3 mentioned OpenGl options are disabled in ccsm which comes at too
great a cost.
(particularly the 'always use buffer swapping' which has proven to be
very effective at removing tearing on video playback, at least with nouveau
