When using analyzers with amarok 1.3.3, and composite with x11-base/xorg-x11-6.8.2-r4, the analyzers show through applications that are on top of them. Reproducible: Always Steps to Reproduce: 1. enable composite 2. start amarok 3. use one of the last three analyzers 4. put an application on top of amarok Actual Results: the analyzer shows through the other application Expected Results: put the analyzer underneith the other application sorry if this is already known, I searched and didn't find any other bugs like it.
I don't think this is Gentoo specific, it seems something due to the experimental nature of the composite extension, nothing we can do about it... This should be reported to xorg developers or amarok (libvisual?) developers.
