Description typingcat 2018-08-11 17:00:54 UTC
I am not entirely sure if this is a bug of Microsoft Japanese IME or Writer, but since this happens with only the first word, I guessed it may be Writer's bug.

*Steps to reproduce
1. Go to Format -> Page -> Page
2. Set Text direction to Right-to-left (vertical).
3. Type some Japanese text using Windows' in-built Japanese IME. 

For words other than the first word of a line, the candidate list (press the spacebar) is displayed to the left of the current line, so what you are typing is not obscured. 

But for the first word of a line, the candidate list is displayed above the characters being typed, so you cannot see what is being typed. The candidate list first pops up to the right of the character, but immediately jumps to the left obscuring the characters.

Hello Shinji,
Would you mind taking a look at this issue when you have some time ?

I am sorry for a separate comment. I did not know that I could add the comment right when adding a new file. It seems that I cannot edit the comment.

I recorded the screen using a free recorder (sorry for the watermark at the centre). This is a freshly installed Windows 10 April 2018 Update (that is, the latest version), and I have not changed anything except that I added the Japanese IME. At first very typing, it did not happen, so I thought it might be due to Kana Input (which I use), so I changed it to Kana Input before recording the screen, but after this recording, I could confirm that it also happens with Romaji Input.

Anyways, at the very beginning, it did not happen but then I changed the mode to Direct Input and then typed a space, and then pressed the backspace to delete it. I am not sure if that is related to this problem or not, but after the first line, this problem continued to happen for all lines without switching the mode.

The video format is "FLV" which can be played with most of the famous video players such as VLC or PotPlayer. I thought that I could have convert it to more popular format such as MP4, but I was afraid that it might degrade the crispness or increase the file size. But let me know if you cannot play "FLV".

Hi typingcat, Thank you for the detailed information.

It reproduced when setting as follows.

1. Select Menu [Tools]-[Options]
2. [Language Settings]-[Languages]
3. Both "User interface" and "Locale setting" are set to English (USA)
To reproduce it was necessary to delete once.

It seems to happen when "Locale setting" set to English.

User interface: English (USA)
Locale setting: English (USA)
-> It reproduced

User interface: Japanese
Locale setting: English (USA)
-> It reproduced

User interface: English (USA)
Locale setting: Japanese

Dear typingcat,

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.
