I see here and there some very minor bugs and visual thingies so I found one of my one. It doesn't need to be fixed but if it's fixed, then another bites the dust I guess.
When you go to the control options, the list ends just before the "start/stop stream" button is displayed.
See screenshot.
All pixels are there, the last 3 rows of the Start/Stop button are a bit darker by the shading effect of the window.
