R5 recording issue

Has anyone else experienced a recording issue similar to what's shown below?

It is the first time I've seen it happen. A horizontal band over 2 frames (file 1488 and 1489). It is not the CFexpress card as I was recording RAW to both slots and the SD card shows the same issue.

Shot in high speed (H but not H+) burst with electronic shutter. Full frame captures (not crop mode).

I shoot in HS ES a lot and don't remember seeing that on any of mine.

Thank you for the feedback, Dave.

Yes, it was very odd - especially since it appeared in the middle of a shooting sequence (not immediately after start-up or after a parameter change).

I will have to chimp more often to make sure that the issue doesn't return. I typically will shoot an entire day without reviewing more than a handful of frames. I enjoy reviewing them at the end of the day with a glass of wine.
