After formatting to A9LH my OLD 3ds has half the top screen darkened. It only happens on the homescreen and nintendo apps. Going to the Luma config screen is fine. Everything before the system "OS" starts is fine, when loading a game, the screen is fine too. When I do a system reset the screen works fine. But then after a while it goes back to the same. See attached pics. I am convinced this is a software issue, since formatting works fine and games work file, just the homescreen and official apps broken. Any ideas on a fix.
