           Summary: [chromium] support the lucid version of freetype on
                    precise in DRT
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: dpranke at chromium.org

Changes in FreeType between Ubuntu Lucid and Ubuntu Precise change how the text in pretty much every pixel test is rendered, causing ~7000 failures when running Chromium on Precise. The currently recommended workaround is to use a Lucid chroot, but it would be nice to run precise natively.

One option is to use two sets of baselines (like we do on the mac), but we'd like to avoid this. Soon (April if not earlier) we'll be dropping support for Lucid and need to update the baselines, but in the meantime it looks like we can simply preload the lucid version of freetype when running DRT and get the same results, so this seems like a good workaround (or we could compile a static version into DRT, or adjust the rpath of the binary). Note that we don't want to change how Chrome behaves; that should continue using the system version of freetype.
