The outline is Invisible with Show Metrics on

When Show Metrics is on,the outline and notes disappear. Show Metrics does not work.

I cannot reproduce this. Which app version are you running, and which View plugins are installed?

Glyphs Version 2.2.2 (827)
There is no View plugins are installed.

Does anything happen in when you turn Metrics on and off?

Is the pink drawing what you see in the edit view? Then you have a reporter plugin installed and active because Glyphs does not uses that color.
