Can confirm now that simply unplugging the USB powered hub and rebooting fixes the Nautilus 1 pixel font problem. Another problem where the built-in display was black and only the TV got wallpaper was also fixed. Plugging the USB hub in after boot did not break Nautilus fonts.
On the hub are:
1) UPS battery status monitor
2) Smartphone
3) Blue tooth ear buds
4) Laser Printer
5) Couple of spare cables
