What is this light/dark usage?
It is extremely disconcerting when the edges of an app suddenly turn BLACK or DARK BLUE while in the process of editing a document.
I have tried searching but there seems to bee absolutely nothing on Apple about though I do remember seeing it during the set up operation.
How can this be mitigated so it remains LIGHT and NEVER turns black/blue?
What really concerns me is that it was turned off until I had to 'force close' an app this morning with this happening on rebooting the system.
