Description Christian Persch (GNOME) 2005-08-07 06:35:56 UTC

Steps to reproduce:
0) Load this document: http://www.zweitausendeins.de/Mh/MH196xxl.pdf
1) On the first page, click-and-hold in the left column, drag down to select
parts of the paragraph

Expected results:
Selection follows paragraph layout.

Actual results:
At first it works as expected, then suddently the selection expands in
unexpected ways; see screenshot. Also note that the selection is drawn
differently while selecting than after a focus out/in cycle (screenshot shows
after; couldn't get one of 'before' since gnome-screenshot causes focus out.).

Cairo + poppler + evince from today (2005-08-06), poppler 0_4_X branch.

Agree, we have a lot of problems with selection in multicolumn documents and
even crashes.

And I can even reproduce "unexpected async reply" X crash with the document above.

I believe this bug and bug 3188 have a common cause. I've posted a patch there which seems to fix the problem, but needs better testing. Hopefully some of the cc list here are interested?

I also have this problem using all libpoppler-based pdf-viewers. But it's not only with muti-colun text, but also with vertical-oriented text and upper or lower indexes. When i try to select a word on a line, which contain these symbols, they are become selected to. It often happens whith indexes in other columns.

Sergey, in the future please do not play with severity, priority nor change the status of the bug to assigned.

Comment 6 Frederic Parrenin 2015-06-24 00:16:21 UTC

I confirm that selection still behaves strangely on some pdf file, especially with multiple columns.
I use evince 3.14.1 and poppler 0.26.5 on debian jessie.
I attach again one file attached to gnome bug #325189 because it is a good test case.
