I have reproduced this right on the day the report came in, but can not reproduce anymore. Could you please try it again? It could be something changed in light-themes and this got fixed. If not, this is something ubuntu-specific as the RGBA theming was an upstream request, see https://bugzilla.gnome.org/show_bug.cgi?id=515907 for the upstream bug request and the bug which seems to be fixed as this bug report exists and this bug and the upstream are totally contradictory.

This is a problem because the more the panel is transparent, the more the System Monitor is difficult to read. All other windows, as far as I have seen, have only the title bar with the transparency. I have attached a screenshot to show you the issue. I don't know if this bug is really related to System Monitor, or to the Ambiance Theme of Unity, but it's the only window affected.
