Right now, the background color of the overview panel's canvas is set to the default OS window background color (on windows and linux, defaulting to a light gray). It can be problematic when working with projects that have a non-white background.
For e.g., in the attached screenshot, I am displaying a set of polygons using a light gray color over a black background. When the layer's [x] show in overview is checked, the polygons can barely be seen as the color matches the OS window background color.
IMO, the overview canvas' background color should match the project's background color.

Nyall, more or less so. The way it was implemented (I think) was to set the panel's background color to the project's background color upon creation of panel or something like that.
The current implementation doesn't deal with project background color changes, or changing background when loading more than one project within a session.
