Deus Ex: Invisible War - Missing geometry, camera zooming

Using dxwrapper with DXIW through Proton on Linux (and subsequently DXVK), getting visual glitches.

Without dxwrapper:

This game was notorious back in the day for alt-tabbing to the desktop during loading screens, and I suspect that might have something to do with this. This is a modded version of the game, but it also happens with a vanilla GOG install.

INI is just enabling EnableD3d9Wrapper and AntiAliasing to 16 (happens with any value). Happens with D3d8to9 as well.

proton-cachyos 11.0-20260521-slr (tried several Proton runners, all the same issue)
NixOS 26.05
AMD Radeon RX 7900 XTX
AMD Ryzen 9 7950X3D
radv [Mesa 26.2.0-devel (git-76fdc60)]

Main motivation for using dxwrapper is the antialiasing as the game's Visible Upgrade mod disables antialiasing. Issue doesn't occur on the last dgVoodoo2 version that works with Proton, v2.79.3.

Would gladly test out any builds. Thanks for your attention and this project!

EDIT: the issue also happens in Thief: Deadly Shadows, which is the same engine/developer:

I believe this is not directly an issue with dxwrapper, but is related to D3d8to9.
