Description

When using non-integer display scaling on Windows (e.g., 125%), unhinted fonts suffer from uneven stroke width and character distortion across the entire UI.

BUG Expected

Steps to Reproduce

1. Set the Windows system display scale to 125% (or another non-integer scale factor).

2. Use a unhinted font.

3. Compared to 100% scaling, character stroke width or sizing appears inconsistent and uneven.

Additional Details

On my computer, only JetBrains Mono and Microsoft YaHei （微软雅黑）display correctly; other hinted fonts also seem to suffer from this issue.

e.g. screenshots, logs, etc
