DawnofWar2 Retribution: Proton Causing Texture Bugs

Decided to be nostalgic and play some Dawn of War 2. Got the special edition on steam which comes with Retribution. The original game works perfectly fine through Proton. The Retribution expansion for some reason has major texture glitches on the character models whenever I run Proton... but I cant play either game without it. Most Fixes I saw on Proton DB were for black screen and crash on startup neither of which I have.

Without proton looks like:

Title Screen, No Proton

Campaign Character, No Proton

but then the game crashes once the loading screen is done and I press any key.

With Proton:

Title Screen, Proton on, Texture Bug

Campaign Screen, Proton on, Texture bug, Goth Phase Tyranid

I did try d3dx9 d3dx9_42 d3dcompiler_42 d3dcompiler_43 d3dcompiler_4 vcrun2005 and other variations in steam settings but nothing changed.

Realized those were for installing. Did that, still no change.
