My English is not very good, so I can only use the translator to translate, please understand. The problem I want to report is that okular has a problem with the position of text annotations when opening PDF files. I guess the reason may be due to the problem of text area recognition, mainly due to the misjudgment of some sentences containing symbols and numbers. I have attached the picture of the situation from the application level.
Created attachment 173725 [details] to descript the error position of comments after opening the PDF file
