Fujifilm X-PRO2: Missing Histogram

There are occasions when the histogram is missing on the Fujifilm X-PRO2:

• Switching from the EVF (Electronic Viewfinder) to the OVF (Optical Viewfinder) without the Electronic Range Finder at the bottom right of the viewfinder and the histogram will be missing for a second or two or…
• Switching from OVF (Optical Viewfinder) with the Electronic Range Finder at the bottom right of the viewfinder to the OVF (Optical Viewfinder) without the without the Electronic Range Finder at the bottom right of the viewfinder.

Half-pressing the shutter button seems to solve the problem of the “missing histogram.”
