Hey there,
ever since I've updated to ungoogled-chromium version 138.0.7204.96 I cannot see any i characters on websites that use this font:
I don't really know who's to blame here, because I haven't noticed this effect with any other webfont so far, so I assume it has something to do with CommitMono in particular. However, I'll cross-reference this issue in the ungoogled-chromium in case anyone there can reproduce the issue and has further insights.
Thanks!
