It's probably still easier to do both (this one and bug 710772) in one patch. If I am not mistaken only a few lines need to be added to nsWindow::OnPaint().
Add
    nsPaintEvent willPaintEvent(true, NS_WILL_PAINT, this);
    willPaintEvent.willSendDidPaint = true;
    DispatchWindowEvent(&willPaintEvent);
near line 1979 or at the top of the function and
    event.willSendDidPaint = true;
near line 2037 and
    nsPaintEvent didPaintEvent(true, NS_DID_PAINT, this);
    DispatchWindowEvent(&didPaintEvent);
near line 2135, before the return.

But feel free to ignore me, since I don't know the code all that well any more, this may be complete rubbish... (I was just curious what this was about.)

OS/2 is an unsupported paltform.
