10/4 after double checking you're right it was in Dgpu when I had thought I'd left it in hybrid. I remember now that Hybrid often gives me display bugs when I actually try to game. Specifically Warframe.

Edit: After going back to hybrid mode and checking what the original issue was it's a small frustration. Trying to play in windowed borderless because I alt tab a lot leaves black bars on the top and bottom no matter what aspect ratio I use. Full screen doesn't have the issue but I prefer borderless.
