KB2545698 - Hotfix to fix blurry font issue in Internet Explorer 9 (and Firefox ≥ 4)
I haven't had this issue myself, but I thought it might be worth posting...
Assume that you install Windows Internet Explorer 9 on a computer that is running Windows 7 or Windows Server 2008 R2. In this situation, text that is displayed in the following core fonts in Internet Explorer 9 appears blurred compared with the same text and fonts in Windows Internet Explorer 8:
- Arial (font style: Regular; font size: 8-point, 9-point, and 10-point)
- Verdana (font style: Regular; font size: 8-point, 9-point, and 10-point)
- Tahoma (font style: Regular; font size: 8-point, 9-point, and 10-point)
This issue occurs because of a design change to how Internet Explorer 9 renders text. By default, Internet Explorer 9 uses sub-pixel positioned ClearType to render text by using DirectWrite, whereas Internet Explorer 8 uses whole-pixel positioned ClearType to render text by using the Microsoft Windows graphics device interface (GDI).
