If anyone wants to take a look at it, there is an OP-X PRO II windows vst http://www.sonicprojects.ch/opxpro2/freedemo.html that can't seem to create a d2d1 factory and then crashes (been tested on multiple systems with different wine wine-staging etc versions with the same results).
That's a separate problem, it's possible it's asking for newer factory interface, we should have some of that done a bit later this year, after Wine 3.0 is out. See bug 43595 and bug 44052. It might be better to open another report for OPX Pro just in case it needs something different later on.
