Is this still Word 2003?
Yes, sorry for not mentioning it.
Does 'winetricks gdiplus' work around the problem?
Yes, it fixes all the problems with equation rendering, including first equation, for which there's bug 21952. (Current one isn't a duplicate because it appeared after bug 32661 was fixed and wasn't present when bug 21952 was reported).
