        <pre>I have an Linux Mint Petra (i.e. Ubuntu Saucy) on a desktop with Intel X4500
integrated graphics (G41).

I installed Google Hangout plugin in Firefox. When I try to make a video call
in google hangout the video flickers (or blanks, not sure what would be correct
term). If I do not move the mouse I see mostly black screen and sometimes see
video. If I constantly move the mouse I see video which sometimes blanks.

Some details:
  - The bug appears in both nightly FF and stable FF but doesn't seem to appear
in chromium.
  - The bug does appear in Oibaf ppa (2:2.99.910+git1403141930.8cc) but doesn't
not appear in stock version of xorg/graphics drives that come with Saucy.
  - I've filed a bug with Mozilla:
<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=984177">https://bugzilla.mozilla.org/show_bug.cgi?id=984177</a> but the fact that bug
doesn't seem to be reproducible with older Intel driver suggests that FF might
not be completely at fault.
  - I use Oibaf ppa because Saucy's stock xorg is not exactly usable on this
hardware due to <a class="bz_bug_link 
          bz_status_ASSIGNED "
   title="ASSIGNED --- - [sna gen4 w/a] corrupt rendering (including wrong rendering of characters and flickering on redraw)"
   href="show_bug.cgi?id=55500">https://bugs.freedesktop.org/show_bug.cgi?id=55500</a> and the fact
that TearFree doesn't see to work there and without TearFree life if very ugly.
  - Yes, I use TearFree, but this bug is reproducible without it.

  I would greatly appreciate if somebody would be interested in looking into
this issue. I have a feeling it might be related to
<a class="bz_bug_link 
          bz_status_ASSIGNED "
   title="ASSIGNED --- - [sna gen4 w/a] corrupt rendering (including wrong rendering of characters and flickering on redraw)"
   href="show_bug.cgi?id=55500">https://bugs.freedesktop.org/show_bug.cgi?id=55500</a> somehow...

  I would be happy to provide any additional information and test anything on
the hardware.

  Thanks!</pre>
