Inconsistent space widths in document paragraphs


When using OnlyOffice online documents, the spacebar width is inconsistent. However, when the OnlyOffice online document is downloaded to the local computer and opened with Office software, the spacebar width is consistent.

The paragraphs in the screenshot are justified; changing them to left alignment makes the spacebar width consistent in OnlyOffice. I believe this is a bug.

Hello! Thank you for reporting this.

Could you please clarify whether the issue is reproduced with any font or only with a particular one? If it occurs only with a specific font, please let us know its name. If this is a custom font, please attach the font file as well.

Also, please check whether the behavior is reproduced in a newly created document using the same text and font, or only in the original document.

Once we have these details, we will investigate the rendering difference.

Font: SimSun, Size 5
Indentation: First line indent: 0.74 cm, justified
Line spacing: Multiple line spacing 1.15 character lines, orphan control

Thank you for clarifying the formatting settings.

We have forwarded the case to our QA team for verification.

We will get back to you as soon as we have more information.
