I've sent in a log D1734497471, but of course once I restarted with logging enabled the issue stopped occurring...

As I said in an earlier thread, this is a rare, intermittent problem for me. I don’t ever use the search utility, thus, one of the precipitating factors does not involve a search-in-progress. Also, at least one of my machines does not auto-sync and this disappearing note problem also happens there when there isn’t a manual sync underway. The last few times that I planned to work with notes, I turned on debug logging. I could edit my notes without a problem. I’ll continue to activate the log each time I’m going to work with notes. I thought that debug logging might slow things down but I’ve not noticed any real delay much less anything bothersome.

I have experienced this bug multiple times (at least five times) today. Here's my most recent error log report number: 1624651714. Earlier today I posted a different error log number when I experienced this problem around the third time and before I discovered this thread. Let me know if it would help to provide that earlier error log number as well.

I have the latest update (Zotero 5.0.31), and I continue to have the problem. Report number: 1751027259

@dstillman As I type text in a note (independent notes as well as notes in the text box section of PDFs or Snapshots), several words and/or whole lines of text will disappear and my cursor will reset at the beginning of the note. Does that explain it? Happy to give more details.

Auto-sync is enabled. The text will disappear regardless of whether there is an active search or not.

Typed text was deleted and the cursor reset at the beginning of the note three times while debug output logging was enabled.

Was any progress made in solving this problem? I've been having this exact problem in Zotero 5.0.53. It doesn't seem to be tied to syncing. It just occasionally happens that the last few seconds of text I typed in a note disappear and the cursor returns to the beginning of the note. Hugely inconvenient. Anything to be done on this?

Here's my debugging report, though I have to say, it's a sporadic not continuous thing, so when I tried to repeat the action, there wasn't actually a problem (D658276473). I guess I could try to have auto-sync disabled, but that's such a critical function that im hesitant to turn it off even briefly.

This issue keeps disturbing me when I am writing text into notes:
1. Start writing text into a note or into the notes field of an attached file.
2. When Zotero starts indexing an attached file or syncing the library, the text written during this process gets deleted.
3. The cursor jumps to the beginning of the line and continues to write from there.

For debugging, I can reproduce the issue like that (Debug ID: D1734287008):
1. I triggered Zotero to index again an attached pdf file (39 scanned pages with OCR text, 1.1 MB).
2. During the indexing process, I wrote into the notes field of the same attached file in Zotero: "This is an important note text." I started typing after some already existing text in the note (= "Existing text.")
3. The indexing process was done after typing "This is an im". These words suddenly disappeared. The cursor jumped to the beginning of the line, before "Existing text." There, I continued to type "portant note text."

As I said above, this happens also during syncing and in normal (yellow) notes.
I am using Zotero 5.0.81 on Ubuntu Linux 19.10.

Update: This happens also when automatic syncing and automatic full text syncing are disabled (Debug ID D1864722419). In this case, I was typing "This is an important note" into the same notes field. "This is an important" disappeared right after the indexing process.

Same problem here, persisting over a year and later with Zotero 5.0.96.1.
Is there no fix?

The symptoms are the same. As I am typing a note, seemingly randomly the recent few lines of text are just randomly deleted. It's extremely frustrating.

I did not have debugging enabled (oops), but I just reported the Error with Report# 1724768459. I have debugging now enabled, so I will have a code.

I have no idea whether I am using an 'embedded attachment note' or how to switch to a normal note. Would love to know how to do that (and what the tradeoffs of doing that are).

@dstillman Thanks so much: avoiding embedded attachment notes is easy enough, and so far as avoided the problem

Looking forward to the new note editor.
