Description icymist 2014-11-04 16:06:19 UTC 
I am using the default Okular on opensuse 13.2.

Highlighting a two-column document (journal article http:dx.doi.org/10.1021/ja3080117) on its first page highlights both the columns instead of just one.

I can attach a screenshot, but I don't know how.

Reproducible: Sometimes

Steps to Reproduce:
1. I guess it depends on the page set up in the pdf. On other pages, I can highlight the columns separately without a problem.
2.
3.

We will need the pdf to fix this.

Yeah, our algorithm gets confused by the first paragraph that is just one column.

Confirmed still an issue on 1.11.3, tested with attached PDF.
Comment 8 Massimiliano L 2021-03-17 11:47:51 UTC 
Problem is still present in 20.12.3, does not happens with all two-column PDFs but it still occurs with the example provided here. Evince on the same document behaves correctly.
Comment 9 Laura David Hurka 2021-07-13 09:38:56 UTC 
Happens with any document, even in .txt with just many spaces between words.

I just selected "However," but the selection became a mess

Yesterday I had to edit a two column document, however Okular sometimes copies the entire line (ignoring the columns). This behavior doesn't happen on Chrome or Firefox. 

I decided to do some experimentation with the raw (without any modifications) template document: https://www.acm.org/binaries/content/assets/publications/word_style/interim-template-style/interim-layout.docx and it seems to be a LibreOffice Write PDF export related issue in tandem.  I believe it to be because if I just download the PDF sample from ACM: https://www.acm.org/binaries/content/assets/publications/word_style/interim-template-style/interim-layout.pdf  Okular correctly copies text as expected. Can't say for sure all multi-columned LibreOffice Write documents exported as PDF will cause this, but all I generated to test had that issue or worse! When selecting a single word, the selection picks the first word of multiple lines! (see attatchment)
