One of the reasons for the slowdowns are the console output. Lines like: fixme:xrender:X11DRV_AlphaBlend Ignoring SourceConstantAlpha 178 for AC_SRC_ALPHA fixme:msimtf:ActiveIMMApp_OnDefWindowProc Stub (0x2005e 20 3006e 2000001) and fixme:shdocvw:InPlaceActiveObject_TranslateAccelerator (0x16fe60)->(0x32fd84) are spamming the console. So i think this bug depends on Bug 15435.
Then try 'wine messenger.exe &> /dev/null' and see if it improves greatly.
The DIB engine in bug 421 may help.
