Had to test Unity 5.2 as it's out! Seems like Gizmos don't render the same way as with 5.1.2 / 5.1.3 - they seem to be rendered like lit wireframe in both editor and game view. This makes it bit hard to see debug rays, capsules and such. Or is there is a setting to change this? Seems like a bug as there's no point to shade debug line renders that often, it only makes them hard to read.
