[BUG] PDF sync stuck in loop when OCR enabled + OCR recalculated on every edit?

What happened?

When using "Sync document PDFs" with Auto sync and OCR enabled, the resync process gets stuck in a seemingly infinite loop (the date of file creation in my file manager changes to the current time every minute + the colored sync bar under the document in the app keeps hiding and showing) and strains + heats up the device until the app is closed. The same thing happens when manually redoing the OCR or when just changing contrast or anything else.

It also seems like the OCR itself is being recalculated every time anything about the document is changed (though I'm not sure), but that is unnecessary as the app already saves the OCR and makes it accessible with the button on the right side of the single page tab. OCR calculation should only happen with brand new pages, because any other page's OCR can already be manually redone using the OCR button from the toolbar.

@Yquas thanks for the report. Will be fixed in next version

@farfromrefug Thanks, I'll take a look when it's released.

Were you also able to test if the OCR gets recalculated at every edit? Adding/cutting/rotating pages should of course trigger that (only for the affected ones if possible), but when you only change colors or contrast, is it that useful or isn't it more of a waste of computing power? What do you think?
Or is it simply necessary to not make the OCR feature overly complex?

And again, I'm sorry for putting all this in one issue, I won't next time.

@Yquas yes it is better to compute OCR with brightness/colors... change because it could be "easier" to OCR the file

Syncing with OCR is now working as it should in v1.19.1 Build 140, thanks!
