When booting a Full Boar 4 from a console restore drive both touchscreens are inverted (i.e. touching the lower left hand corner moves the mouse to the upper right corner, and vice versa). Once the install is complete and the console boots into the normal OS the touchscreens behave normally.
This occurs on both of our Full Boar 4s but none of our other consoles. Flash drives that exhibit the issue on a Full Boar, will work normally on another model of console and vice versa.
To reproduce burn a flash drive with the console restore iso, then plug it into a Full Boar and boot the console.
