Thank you for reporting the bug.
Could you please try to reproduce it with the latest version of LibreOffice from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the latest version.

Reproduced in 7.2.0 & 7.1.5.

Version: 7.2.0.4 (x64) / LibreOffice Community
Build ID: 9a9c6381e3f7a62afc1329bd359cc48accb6435b
CPU threads: 8; OS: Windows 10.0 Build 19042; UI render: Skia/Vulkan; VCL: win
Locale: ja-JP (ja_JP); UI: ja-JP
Calc: CL

Version: 7.1.5.2 (x64) / LibreOffice Community
Build ID: 85f04e9f809797b8199d13c421bd8a2b025d52b5
CPU threads: 8; OS: Windows 10.0 Build 19042; UI render: Skia/Vulkan; VCL: win
Locale: ja-JP (ja_JP); UI: ja-JP
Calc: CL

But it seems to occur not only with Western Font, but also with Japanese Font like "Noto serif CJK JP" in my environment.
There seems to be a problem of degree, and it seems to be better in 7.2.

Could it be a problem on the IME side?

Dear S.Nakai,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
 
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword
