Symptom

There are reports of blurry or unclear CJK (Chinese, Japanese, Korean) text when displayed at 96 DPI (100% scaling) in Chromium-based browsers such as Microsoft Edge and Google Chrome. The March 2025 Preview Update introduced Noto fonts in collaboration with Google, for CJK languages as fallbacks to improve text rendering when websites or apps don’t specify appropriate fonts. The issue is due to limited pixel density at 96 DPI, which can reduce the clarity and alignment of CJK characters. Increasing the display scaling improves clarity by enhancing text rendering.

Workaround

As a temporary workaround, increase your display scaling to 125% or 150% to improve text clarity. For more information, see Change your screen resolution and layout in Windows.

We are investigating this issue and will provide more information when it is available.
