Bug #: 30593
           Summary: Riched slow at appending text
           Product: Wine
           Version: 1.5.2
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

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.

Same test app, using plain old multiline edit control instead of richedit

The same test done with a plain old multiline edit control
is only 10% faster than richedit.

Looking around for a workaround that app vendors could use, I hit on the
idea of using WM_SETREDRAW to disable redraws during big richedit changes.
With native riched20, this can speed things up quite a bit.  Builtin
riched20 doesn't seem to support it yet (it hangs).  
I should file a separate bug for that.

Fun fact:
ME_InvalidateMarkedParagraphs calls InvalidateRect about a bazillion times.

See bug 30614 for the hang (well, really just big slowdown) when appending text
to a hidden richedit control.

This bug is a bit messy - I'm going to file a cleaner one for the remaining
problem.
