git-bisecting compiz pointed me to this being related to the translucent
cube feature, and I discovered that
the /apps/compiz/plugins/cube/screen0/options/inactive_opacity gconf key
was set to 90. Changing it to 100 restores sanity for me. Not sure how
it came to be less than 100 in the first place, but if it can happen by
default that should probably be fixed.
