When the panel is transparent the Indicators are still shown on a solid background, for *some* themes.
To recreate this issue you'll need to use Ubuntu MATE 16.10 daily with all updates applied. Then use MATE Tweak to Enable Indicators and make the panel transparent.
* From `ubuntu-mate-artwork` only the Ambiant-MATE theme is affected. Radiant-MATE works correctly.
* Most themes from `mate-themes` 3.20.12 behave correctly although TraditionalOK and TraditionalGreen exhibit the issue.
