Damn. Ok - so just to confirm a couple of things while I think about this:
- the flickering happens with and without the 01.org installer updates?
- youtube videos flicker when played via both flash and html5 video?
- does anything of interest turn up in dmesg or xorg.log while youtube videos are playing?
1 - Unfortunately it happens with or without the 01.org driver.
2/3 - Youtube videos were just an example... it happens everytime there's movement on the screen (scrolling through webpages is another example).
Out of immediate ideas - anything in dmesg that looks like video errors? Timeouts, interrupt problems, that sort of thing? I'll pass the symptoms on to the devs and see if they suggest any useful avenues for further investigation.
