Windows Terminal version

1.24.3504.0

Windows build number

10.0.19045.6691.amd64fre.vb_release.191206-1406

Other Software

Graphviz 14.1.1

Steps to reproduce

Running dot.exe -Tpng with a .dot file using [fontname="Sans italic"] (or [fontname="Segoe UI Italic"]) produces warnings.

This was not the case before Windows Terminal.Preview v1.24.3504.0

This doesn't repro with Windows Terminal 1.23.13503.0.

Switching to software rendering makes the warnings disappear.
