Primitive drawing elements such as lines, circles, and rectangles rendered with active anti-aliasing on Garmin Edge devices appear to be anti-aliased against a white background, even when the actual background color is different. This results in visible white border artifacts around the rendered elements.
I tested this with the latest SDK and was able to reproduce the artifacts on my own Edge 850, as well as on another user's Edge 540.
The issue may be related to similar artifacts observed when rendering glance icons and glance fonts: #259
