It is not a known or reported issue. If you want it reported to Engineering you would need to go through 2nd level support. They would need configuration sheets and try to replicate the issue. But I do not believe they will be able to, which would end with them wanting the machine wiped and setup manually.
The other choice is to downgrade to the older firmware on the other machine, but with that you would likely go back to the previous issue with color.
In my opinion I would skip the initial 2nd level support call and just go with the tech upgrade, have the tech do a "Forced Altboot no data backup" to the 072.040.145.05000 firmware then setup the machine again manually. Under no circumstance try and restore anything with a clone file, the only thing you could backup and restore would be the Address book, and or Xerox Standard Accounting, which would be done outside of the clone area in CWIS.
Realistically, I think just about every avenue available through support will end up with the device being wiped eventually, the plus would be, that once it is done, and working perfectly in the environment, you could then have the other one brought up with the same method to the same firmware, and once complete, you could then clone this one onto that one because they are the same model on the same firmware.
