           Summary: [freetype] uneven rendering quality when bytecode is
                    enabled
           Product: Fedora
           Version: 15
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: unspecified
          Priority: unspecified
         Component: freetype

    Classification: Fedora


Description of problem:
After updating to the latest FreeType build for which the bytecode interpreter
has been enabled, fonts are rendered with uneven quality. The system font used
e.g. for button labels is very thin now and certain popular web fonts (e.g.
Verdana) are rendered surprisingly poorly.
Look at the four attached screenshots which demonstrate the various
combinations for which the bytecode interpreter is enabled (disabled) and
webcore fonts are installed (removed).

Version-Release number of selected component (if applicable):
freetype-2.4.4-3.fc15

How reproducible:
Always.

Steps to Reproduce:
1. Launch firefox.
2. Open http://www.bbc.co.uk .

Actual results:
Partially poor rendering depending on whether the bytecode interpreter is
enabled or not.

Expected results:
Acceptable rendering quality throughout all font families.

Additional info:
Reverting to freetype-2.4.4-2.fc15 restores globally good font rendering.
