I use the latest Pixelmator 3.9 Classic (91112.1319) on the latest MacOS Catalina 10.15.4 and have noticed this issue for quite some time. I'm not sure if the occurrence of the issue is continuous or random. As the attached picture shows when a JPG file is opened with Pixelmator the bottom edge color is lost, compared to opened with Preview.

Interesting, would you be able to upload that JPEG for us at http://upload.pixelmator.com, then copy and paste the link that appears on that page here? Thanks in advance!
