(Get the code!)
Apologies, that should have been "1-2 second video".
Also, for what it's worth:
Back on 11.04 I tried out Nautilus Elementary with Clutterflow (am-monkeyd ppa). It never worked right, displaying similar artifacts in the ClutterFlow region -- so much so that it was unusable. I long since removed it and the am-monkeyd ppa. Same machine and hardware configuration.
Within the ATI Catalyst Control Panel (amdccle), I have tried both tear-free enabled and disabled, as well as just vsync on blank both enabled and disabled (tear-free forces vsync on blank, so tear-free is some superset of that). None of the settings resolve the problem with shift switcher (nor did it with ClutterFlow).
Lastly, if you look at the screenshot I posted in Comment #7, the corruption on the topmost right-hand side of the panel (but not menu bar), you'll see the remnants of Alarm Clock 0.3.2 applet/indicator. This window pops up when I first login. I close it right away, and had not used it since logging in (hours previous).
Thus, my suspicion is that the artifacts are related to some double (or triple) buffering issue within or between OpenGL and ATI's fglrx drivers, or at least in the way Shift Switcher is calling them. I suspect the was true with Clutterflow back on 11.04.
This issue is annoying, but what's worse is that it makes it more difficult for me to "market" to friends and colleagues. :) Looks terrible.
I always used Nvidia on Linux up until summer of 2010. I think I'm down with ATI and will go back to Nvidia.
I am curious: Is anyone else here having these problems on non-ATI video hardware?
Thanks. --Doug
