Comment 12 for bug 270377

Same problem. Fresh install with 2008-10-14 AMD64 Daily-Live image, all updates.

Notes:
o Most apparent in the Compiz Settings Manager. Every page change requires a force-redraw (see next point). Also, freezes a bit every time a change is made in the settings, along with high CPU usage (I suspect it's reloading the plugin with the new settings, but it seems a bit less 'agile' at it than in Hardy).

o Redraws can easily be 'forced' by clicking the title-bar of the offending program. Not sure why, but useful.

o Usually seems to happen in clusters and/or associated with particular programs (Compiz Settings and Appearance in particular).

Haven't noticed much in firefox (but I mostly use the mouse) other than an effect that was also in Hardy:
o When opening a previous multi-window session (including at firefox start), some/all (varies) firefox windows won't paint until minimized or maximized, showing garbage from the initial animations.
