Original issue's description:
> Linux Aura: get tooltip background color from theme
> 
> the border color can still conflict with the theme (e.g., no visible border if the tooltip bg is dark), but fixing that is a lot harder because the border, window roundedness, and shadow are all one tiled set of images (see shadow.cc).
