My 340.24 joy was short-lived it seems.
While the flickering/wiggling issues are vastly reduced compared to previous

now its bearable with the issues only appearing at random times spaced
nv 340.24 got pushed to the xserve ppa yesterday and I updated to 340.24 and

to the flicking of random UI elements.
