--- Comment #3 from Dennis Groenen d.groenen@student.fontys.nl 2011-06-05 11:50:56 CDT --- I can confirm this bug. I've noticed extremely laggy scrolling and letters appearing visibly later than typed in complex Word documents since a long time ago now. It really makes using Word 2007 somewhat unbearable.
The issue persisted after downgrading wine to 1.3.18, but disappeared immediately after downgrading to 1.3.17, so some commit between those versions (presumably the one pointed to by the reporter) is definitely the cause of this bug.
