Since the last update we have had problems with all static images in JA Builder. Any module that we're using that incorporates a static image seems affected. In edit mode everything looks correct but once published all images are stretched vertically. Video seems unaffected.
This was an issue with the last update, and we posted a request for a bug fix then. Someone kindly logged in and fixed the issue with our site but the issue has returned since we upgraded again. Whatever the root of the issue is, it's still present and is over-writing whatever was repaired in our installation.
