I am experiencing an issue with the auto-correction feature in the document editor. The automatic text correction disappears while using the program and only reactivates after closing and reopening it.
Sorry for the language used. I tried to better understand the problem and noticed that at the bottom right, the language is set to Italian when the program opens, but then it gets deactivated as soon as I start typing.
P.S . I installed version versione 8.3.2.19 (deb), but the problem persists.
On your screenshot the text language gets hidden, but not the auto-correction. Taking into consideration documentation about spell-checking in document editor, please try selecting a text passage and setting up necessary text language manually and see if after that the issue reproduces.
If your document in written in a single language, you can also test as follows:
Select whole document content with CTRL+A;
Set necessary text language (drop down menu with languages) and document language (globe icon);
Try typing text in the language that was set up.
You can also create a copy of your document specifically for test, if you do not want to change anything in the document.
