[Wine] Guild wars 2 and other translucent windows

[J V]

How's wine support coming with translucent windows?

Guild wars 2 has a new launcher that makes extensive use of transparency to mimic the in-game interface, but of course, it turns into a massive black square here.

Screenshot of the launcher, all that is black is supposed to be transparent:

I know it's nitpicky but google implied some progress on this and I wanted to know if I was just doing something wrong.
