I noticed some funky bizniz with the cursor in version 1.07 UEFI. The cursor is stuck to the sides of the monitor or top bottom edges. When moving the cursor into the centre of the display it instantly gets sucked back to one of the edges dependant on the direction it was moved either top bottom, left/right.
Disconnecting the mouse USB port and reconnecting it alleviates the issue until the next time of dropping into the UEFI.
