Comment 111 for bug 314928

I have a MSI MS-1223 (PR201) laptop, which has an Intel GMA X4500 graphics chip, with Ubuntu 9.04 (32-bit) on it.

I fixed the choppy fullscreen Flash playback as follows:

1) sudo apt-get install compizconfig-settings-manager
2) Click "General Options"
3) Remove the check from "Unredirect Fullscreen Windows"

Flash videos should now play smoothly in Firefox in fullscreen mode. I switched to Metacity at this point because my Conky monitors were flashing during playback withh Compiz as the window manager. If you don't use Conky, you shouldn't see this flicker. Use whatever window manager you want.
