Description: I am using Japanese input method coming with macOS. Everything is fine at first. Then after I type around 100~200 Japanese characters, the UI becomes laggy (the cursor responds slower, and it takes longer to respond to my keys). After restarting the software, everything is fine again, even though there is a lot of Japanese characters on the page. The problem happens again after I type another 100~200 Japanese characters. Steps to Reproduce: 1. Open a new document (.docx format) 2. Type a few hundred Japanese characters using macOS's Japanese input method 3. Try to move cursor or type, it should be lagging. Actual Results: The software becomes laggy Expected Results: No lag Reproducible: Always User Profile Reset: Yes Additional Info: I did not install any extensions and I tried in safe mode. It still lags. I reproduced it in 7.0.5.2 and 7.1.1.2 MacBook Pro (Retina, 15-inch, Mid 2014) OS version: macOS Big Sur 11.2.3 processor: i7-4980HQ memory: 16GB graphics: Iris Pro, GeForce GT 750M
The font I am using is Noto Sans
I tested with Catalina ver 10.15.7. I could not reproduce it. There was no lag after writing more than 200 and more than 600 Japanese characters.

Thanks for testing it. I am running on Big Sur (11.2.3) so it could be a problem only on Big Sur. Also, my further testing shows that the UI already becomes laggy with a few thousand Japanese characters on screen without doing anything.

I tested it with Big Sur (11.3). But there is no lag with typing and movieng cursor. LibreOffice version : 7.1.1.2 Mac mini (2018) 6core Intel Core i7 3.2 GHz 32 GB boot SSD 1TB macOs Big Sur (11.3) Japanese Input method : ATOK
Hi, I found what is causing my lag. Previously my typed Japanese was recognized as Chinese (simplified). Now that I changed the text language to Japanese, the lag stopped. I'm not sure if this is expected behavior, but thanks for the help!
@peigil: can you please copy & paste your about settings to this bug. Am I understanding correctly, that you would consider the expected behavior that LibreOffice manages to correctly detect the (already used and existing) japanese language in the file in question. Is that problem reproducible with other writer documents for you? Are they all falsely detected as chinese (simplified) language?
Version: 7.1.2.2 / LibreOffice Community Build ID: 8a45595d069ef5570103caea1b71cc9d82b2aae4 CPU threads: 8; OS: Mac OS X 10.16; UI render: default; VCL: osx Locale: en-US (en_JP.UTF-8); UI: en-US Calc: threaded The recognition is due to me setting Chinese as the default Asian language, so it's not a bug. I am just not sure if it is expected that incorrectly detected text language would cause so much lag.
Tested with macOS 11.3, worked fine. I got no problem at all. No lag. LibreOffice version : 7.1.1.2 Build ID: 8a45595d069ef5570103caea1b71cc9d82b2aae4 MacBook Air 2013 dual core Intel Core i5 1.8 GHz 8 GB DDR8 macOs Big Sur (11.3) Japanese Input method : macOS's default
This is strange. Now I installed 7.0.5 and now the there is less lagging in general. I tried to have part of the text set to Japanese and the rest as None. When I quickly scroll to the Japanese part, there is an obvious lag in scroll animation. Then I set that part also as None, and when I scroll to that part there is no lag at all. This problem only happens with certain fonts like Noto Sans. When I am using the default Japanese font (Hiragino Mincho ProN) there is no lag.
1. switch macOS system preferences > keyboard > input sources to Japanese > Japanese - Kana (Romaji is also offered, @peigil can you elaborate which input method you are using, when lagging occurs please) 2. open LO and save document to docx format 3. LO switches to "Songti SC" font and no lag can be detected 4. switch to "Noto Sans" font No lag scrolling, no lag typing. No repro for me. @peigil: Can you please retest with LO 7.2.0.2 on macOS 11.5.2 and see if the problem persists for you.

And if the problem is reproducible could you please test the same fonts in Apple Writer and see how that behaves for you.
