This is also being discussed here: https://discussion.evernote.com/topic/116459-black-artefacts-when-scrolling/. The latest update to Evernote (released today) didn't fix this.
I have this issue exclusively on Dark Mode. The alternating colored rows are terribly annoying, and illegible—I can barely see the white text on light grey background. The contrast with dark grey rows is an eyesore. I hope these changes are removed. For the record, using the above post's suggestion to change accessibility did nothing to solve this.
