How do I fix display issues on macOS sequoia 15.3 Lock Screen?

Since updating to macOS sequoia 15.3 I've had several issues with the display.

1. The Lock Screen shows black at the bottom 1/8 and everything is shifted up (image attached)
2. Notifications don't display on the edge of the screen, instead they're 1/8 of the screen indented
