Xorg crashing on login - LightDM & XFCE / Plasma

I'm running into issues logging into my headless seat (seat0) after updating my Arch system a couple of days ago. My other seat (seat1) is working just fine.

Basically, I'm able to get to LightDM without any issues, but login attempts black screen and then loop back to LightDM's login prompt.

seat0 is using an AMD RX570 in headless mode (xorg dummy display) and I'm connecting via nomachine.
seat1 is using an NVidia 1060 and is connected to an HDMI display.
