Reminder that this breaks basic features like copy/paste, drag-and-drop, and a lot of applications that spawn helper applications and expect them to be on the same display.

There is a reason that the general Linux desktop camp is not adopting solutions like this and instead preferring Wayland, and that's that these systems can never be production ready and support the featureset that traditional X11 can support.

Also, I tested my keylogger [0] on this setup, and it still got through. Oops. They're proxying through XRecord and XTest it seems.
