Targetting for lucid. There is a workaround by choosing "background image" and no picture, or setting "transparent background" and 100% opacity, but it's a bit non-obvious.
Ideally, if you are using a theme with a transparent background, the profile editor should show "transparent" with the appropriate level, not "solid background". Switching to "solid" should do the right thing then.
