This is happening for me as well, though I thought it was due to the new
nvidia driver 319.23 in the xorg-edgers repo. Turning off hardware accel
in the flash settings brings it back to normal. I'm using gnome-shell
and ubuntu 13.04.

Title:
  awkward color display on video

Status in “nvidia-graphics-drivers” package in Ubuntu:
  New

Bug description:
  There is screen corruption (though non-invasive), when playing flash
  video playback (latest using flash with ubuntu's canonical repo).. I
  don't think it's a flash issue because I get very limitted E-did
  scanning in the X log and because of what's in ~/.xsession-errors
  (attached is my x log)

  (When video is played back on youtube for eg, people's skin color appear blue 
  -- not all of them, for eg, on these two are problematic and didnt have to 
look far from youtube's front page

  -- I know flash is being used (and not html5), because I can do rt-click and 
get the flash context menu (flash edition trivia- 11.2.202.236)
  --Using gnome-classic (no effects) (sorry I'm not using unity and didnt try 
with unity, I'll report if it works fine under unity)

  )
