I normally open S3 data using the 3rd option in the drop down menu. When I open up a file at 1km resolution, the product looks very odd, with ‘long’ elongated pixels. Opening a product at 0.5km resolution appears normal. Is there some sort of bug?
Can you show a screenshot of what you are seeing? I can’t find such pixels.
Which product are you using and from where have you downloaded it?
