Export View as Image in SNAP corrupts some part of the image

Mmh hard to suggest something. The problem can have several sources. As you already suggested often this is an memory issue. It can also be a problem in your processing chain, but then usually different errors occur. Some things which might help: When exporting the image, chose ‘Full resolution’. Save the processing results to disk and open them again. Then do the image export. Create a subset which contains only the band you want and then use File / Export / GeoTIFF from the menu.
