Okular and Foxit displaing the same pdf and selecting the same text

Hello!
I have a problem with okular in the last few days, and I have a suspicion that might go not only with okular as pdf app. So I have some pdf with scanned and ocr books, but the okular does not shows them right. It knows it is text there because I can select it, but it shows it like selecting white or invisible text. Firefox and Foxit shows them right, but Okular does not, and I tried Evince and it does the same thing. I attached some examples too.

It's impossible to fix the bug unless you attach a file to reproduce this issue.

This is most probably a poppler bug, needs investigation
