Same issue. The font after the update is really hard to distinguish.

As far as I am aware, Qt selects the default system font, and it reportedly selected YaHei when the system is set to Chinese locale according to reports from 2022. There were some QTBUGs opened regarding font shaping/kerning issues with YaHei, but those have been marked resolved.

This is a test Qt 6.6.2 app that I quickly wrote (matching Qt 6.6.2 in OBS Studio 30.1.0, per the OP's log) that just displays the selected application font
test-qt-font-family.zip

If you could check if this value is what you expect, that would be helpful to know, but my current suspicion is that this is a Qt issue and not an OBS issue.

The sample app reports expected "Microsoft JhengHei UI" in Traditional Chinese environment.

Report the expected "Microsoft YaHei UI" in Simplified Chinese environment.

@norihiro Sorry for the ping, but need your confirm in Japanese environment.

[norihiro]

It shows Yu Gothic UI on Japanese environment. It's (probably) the system default fonts.

If I have time, I'll see if I can get the same test to run in OBS to see if somehow something is amiss.

[ChrisKimZHT]

same issue, current Songti is hard to read on the screen.

You can fix it by using a custom theme:

Put this in your themes directory, restart obs and select 'Yahei'. You can also change the theme extended from if you want to use other default themes.

Wiki - Custom Themes

Location of themes directory

• Windows: WinKey+R > %APPDATA%\obs-studio\themes\
• macOS: Cmd+Shift+G > ~/Library/Application Support/obs-studio/themes/
• Linux: ~/.config/obs-studio/themes/

You may have to create the themes directory yourself.

This is the same solution as #7390 . Unable to fix issues in non-SChinese environments.
