Horizontal Line Artifacts in PNG Exports where transparency exists on macOS

InDesign export to PNG has a bug. It renders PNG files with horizontal lines where transparency exists. The checkbox for "transparent background" seems to get rid of these lines but not consistently. Also, it doesn't matter if there's truly a transparent background (empty page) or if there's a solid shape in the background. This is not a new issue but has been going on for months if not years. I only recently discovered it was happening and affecting my teams output.

For what it's worth, I'm on Mac OS. Not sure if this issue exists on Windows, too.
