EOS R Areas of Image Flash Black

[ViperEye]

re: EOS R mirrorless
Some white areas of pictures flash black, on and off. Kinda looks like a film negative. Is that something that can be controlled in the Menu or is it an in-need-of-repair problem?
Thanks, Jake

That sounds like an option.  It could be that the saturated highlight alert has been enabled.  You will most commonly see it in the bright sky of a backlit scene.  The setting is in the blue playback menu screens.

The "saturated highlight alert" was the key clue. In Menu:  Play icon; option 3; Disable Highlight Alert.
