           Summary: Riched slow at appending text
           Product: Wine
           Version: 1.5.2
          Platform: x86
        OS/Version: Linux
            Status: NEW

          Priority: P2
         Component: -unknown

Wine on Linux takes about 3 times as long as Windows to run
the attached test app, which just appends 5000 short lines to
a richedit window.

Unlike bug 13355, native riched20 does not work around this problem.
