PDF comparison output is overlapped in .NET

I’m using v18.11.0, release notes show fixes in earlier versions, like this:

COMPARISONNET-1523 PDF Comparison - scrambled/text overlapped output

But that’s exactly what I get. I do have pdf’s with flowing columns (3) per page, if that matters. Output is useless.
