Description K.F. 2021-08-31 14:22:54 UTC

Description:
Vertical Japanese character strings are misaligned when exporting PDF.
Horizontal writing and single-byte alphanumeric characters will not cause any misalignment.
I have tested it on Ubuntu 20.04 and Windows 10, and it happens on both of them.
It does not occur in the stable version 7.1.5.2, only in 7.2.0.4.

Steps to Reproduce:
1.Create a new document in LibreOffice Calc.
2.Right-click on a cell and select "セルの書式設定"(Formatting cells...) to open the formatting window.
3.Go to the "配置"(Alignment) tab.
4.Enable the checkboxes for "縦書き"(Vertically stacked) and "日本語縦書きレイアウトモード"(Asian layout mode) in it.
5.Enter a few Japanese characters in the cell with this setting. (At this point, setting a border for the cell will make it easier to see the misalignment of the string.)
6.From the "ファイル"(File) menu, select "PDFとしてエクスポート"(Export as PDF) to export the PDF file.
7.Open the generated PDF.

Actual Results:
The PDF is generated with the vertical Japanese text slightly lower than the preview in Calc.

Expected Results:
It should have been drawn in the correct position, just like the preview in Calc.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
This bug occurs only in 7.2.0.4, even if the document file with the same content is used.
