7.11 Artefacts at horizontal datafield dividers

From Time to time I'm getting a dashed line instead of a normal horizontal line between data fields.

When I change the page and go back the line appears normal.

On my run today I immediately made a screenshot by pressing a therefore configured hot-button on my watch - interestingly the artifacts only appear on the screen, not on the screenshot. Unfortunately I didn't have my phone with me so I wasn't able to make a photo of the screen.

There was no workout or route activated when it happened, but I was hearing music with the CIQ Spotify App.
