Seems related to bug https://bugs.chromium.org/p/chromium/issues/detail?id=621258 and https://bugs.chromium.org/p/chromium/issues/detail?id=794096

I see the overlap with Letter size paper but only in portrait orientation, not landscape. 67.0.3396.79 on Linux.

We can probably reproduce this with https://www.w3.org/TR/css3-page/ or https://www.w3.org/TR/css-break-3/ without needing to check print preview.

Paul, thanks for reporting with such a good reduced test case (difference between correct and incorrect is that incorrect has slightly less text). Barring external contributions to the open source layout engine (which we do get from time to time), we probably won't get to this anytime soon. I.e. _minimum_ time until a fix hits the stable channel is probably end of 2018. So you're probably best served by investing in determining a css workaround for your use case. And if you do find one, mention it here, which could help us find the root cause.

I forgot to mention: It seems that columns with different content/size causes this issue. In the correct test case all columns have the same content (size).

I have almost the same problem. My finding could help resolve the problem.
I think there is the problem with a line which have rowspan and part of data are multiline (rowspanned) and part not.

Steps to reproduce the problem:
1. Open attached html file
2. Open Print preview
3. Set format: A4,
       margins:
          top 25mm,
          right: 15mm,
          bottom 25mm,
          left: 15mm,
      landscape orientation
4. Scroll to page 2 (problem)
5. Scroll to page 4 (css workaround)
