Ozone in Wine 4.3 (GUI not working)

Since Wine 4.3 Staging, the VST plugin iZotope Ozone shows a black window
instead of it's GUI (both version 7 and 8). It shows correctly on Wine 4.2
Staging.

It may be related to the d3d or d3dx9 components because the plugin uses them
to render it's GUI.

Both logs attached are Ozone ran in FL Studio with
WINEDEBUG='+d3d,+d3d9,+loaddll'. In both logs I did exactly these steps: I
opened FL, loaded the Ozone plugin, closed the Ozone window/GUI and then closed
FL. The relevant part of both logs is after the loading of iZOzone8.dll.

There's a similar discussion about a 4.3-staging regression involving a black
window mentioned in bug #24983, but I'm not sure if it's related because
neither d3dx or D3DXLoadSurfaceFromMemory show up when ran with
WINEDEBUG=+d3dx.

If it's indeed d3d or d3dx9, possibly one of these commits has something to do
with it?:
