When I enable EXA acceleration for my video driver (instead of XAA) none of the progressbars in Clearlooks show the stripes. I'm attaching a screenshot. According to the Clearlooks developers, this is most likely a cairo and/or XRender/EXA bug. I'm using Cairo 1.4.12, gtk-engines 2.12.2 and version 6.7.197 of the radeon driver.

Same symptoms, same hardware, same use of EXA. (Resolving as a duplicate of the newer bug rather than the other way, since the other bug is on the right product/component.) *** This bug has been marked as a duplicate of bug 14645 ***
