With transparent launcher, appmenus/titles don't hide but become black

[Péter Trombitás]

When I set the panel's opacity to 1.000 (so it's totally transparent), the application menus/application titles do no hide when they should, they become black. This problem doesn't occur when the opacity is 0.
It was not a problem before the upgrade to unity 5.2.0.

Aha, it only happens when the opacity is set to 0.0000 any value higher and the issue does not happen.

[Sam_ (and-sam)]

Confirm #2 with bug 926368, opacity 0.1000 no issue, opacity 0.0000 ugly overlay.
