My little contribution,
Happens here too. X-Pro2 FW3.10, all lenses with the last FW today
o 23F2, 35F1.4, 10-24F4, all these shows the same bug.
o 56F1.4, 55-200F3.5-4.8 the MF bug DO NOT APPEARS.
Common point. Short focal length MF bug appears. From Normal (35) to Wide Angle (10-24).
It seems that in telephoto there is no issue.
