White pixels along the left and lower edges of the preview image in portrait format

This is in version 11.0.0.83 (the newest per date).

Images previewed in portrait format shows white pixels outside the native camera format (Sony A7R3) as well as after a crop. So far I have only observed this along the left and bottom side of the image, and not in the landscape format. It's of corse just a cosmetic problem, but it should be corrected.
