No matter what I try, I can’t for the life of me to get image files that are not corrupted. I tried different encodings: jpg, png, gif and bmp, and the saved files are always corrupted.

Note that I can see the image preview which looks fine, and I can also see live streaming just fine, but every single export results in a corrupted image, no matter the file format. I tried to open the image files with programs like sxiv, gpicview, chromium, etc… but to no avail.
