Setting Font-Asset instead of Font for text results in background when font is bold

Recently, we switched from setting the “Font” to setting the “Font Asset” for text (mainly, because some Warning was shown 100+ times in the logs and I thought, it was the source of another bug).

Since then, we see a strange background whenever the font is bold.
It does not alway happen, sometimes only on the Windows build, with preview.17, it’s also happening in the Editor.
Here are some examples:

Could it be related to the Font Asset creation? Does UI Toolkit require special settings?

It’s the first time we see this issue. Could you submit a bug report with a repro please? Go to Help > Report a bug… and post the case number here. Thanks!

I found a workaround for this.

Setting an additional font asset for bold fixed it:
