Hello v.condratiev,

Can you share screenshots of the current behaviour, and the expected behaviour?

We have a different text selection mode called “Rectangular” you can set it like so:

Hello Tyler,
Yes, of course.
So this is the actual text that I’m trying to select.

I can’t select that vertical / sideways text.
I noticed that this happens for all vertical/sideways text and it does not matter what document I use.

If I try to open the file with PDF.js or PDFTron, this works properly.

Best Regards,
Vadim

Hello v.condratiev,

Using test files on my end, which have sideways text, I am able to select them. I have a feeling this could be a file specific issue. I see you noted you cant provide the document, I could give you my email for which you can send the file if you would like.
