Description astyh83 2014-07-02 06:31:39 UTC
Writer gets very slow when typing footnotes. I need to wait an average of one to two seconds for each letter to appear as I type. The situation gets worse when I type in Chinese and use Zotero to add citations. 

Typing in the main document section does not present the same problem.

Dear astyh83,

Can you please provide us with the version of libreoffice that you are running and possibly a sample document where you see this behaviour happening.

Hi astyh83,

I didnt notice any problems typing english, but noticed some slowness typing arabic in the footnote. But then i opened a new document and typed in arabic there and also noticed the typing was slow. So is the typing slow even when not in the footnote?

Hi Jay, 

At was reasonably faster when typing on the main document. I would not ssay that was 'slow', but the lag was tolerable. 

Also, the full-width punctations in Chinese do not align properly, which makes the document look ugly. I don't know whether this is apparent in Arabic as well. 

Will be filing another bug report for this issue.

Did some more testing and i see that whenever i press space bar, there is a delay to show the next word's letters. Tested it on Windows as well and it has the same issue, as i thought it might only be Linux only. Also thought it might be font related but it was the same when i used Tahoma or Droid Arabic Nask. Also thought it was AutoSpellcheck related, but disabling that didnt change it.

Steps to reproduce:
1) open writer
2) switch to arabic or asian keyboards
3) type random words quickly

@suokunlong: can you check if this happens with you as well in chinese.
Comment 6 astyh83 2014-07-07 06:21:14 UTC
Yes, it does.

Forgot to mention that if i type in arabic on libreoffice which doesnt have the arabic dictionary, it will type quickly, but if the dictionary is available it is slow. But from what i can see, there is no chinese dictionary, so i dont know why this would be effecting CJK typing.

I assume the report was closed because the issue is gone.
Adjusting status to WORKSFORME, since the commit fixing the issue is unknown.
