Metapdf shows black pages on some articles


when I open pdfs of articles from paperpile, I sometimes get part of the article blacked out like so:

I don’t see a pattern. Scrolling sometimes seems to exacerbate it, sometimes it happens when I have multiple articles open. Sometimes it is reproducible (i.e. re-opening the same article leads to blacked out pages again).

Would be nice if it didn’t do that.
