Forerunner 255 Display going white during start of activity and changing fields

Within the last month or more, when a new activity is started, the display goes white briefly then shows the data correctly.

When changing data fields on an activity the display is completely white and I can't see the fields to choose from.

I've tried turning it off, removing and reconnecting from Garmin, updating software. I have not tried resetting the device completely.

Has anyone encountered this?
