The missing cursor was caused by the Kensington trackball not yet being registered due to a USB enumeration timeout on a sibling hub port (usb 3-3.4.4, error -110). The cursor appeared once the timeout completed and the mouse registered. MUTTER_DEBUG_DISABLE_HW_CURSORS was not needed and has been removed. The real fix is /etc/modprobe.d/usb-timeout.conf setting usbcore initial_descriptor_timeout=2000 to reduce the per-attempt timeout from 5s to 2s.
