Found from where it comes from:
DXVK 1276 → black textures
DXVK 1275 → no black textures
So the regression comes from this commit: https://git.froggi.es/doitsujin/dxvk/-/commit/f88f424da47ae9631c781165f3809e42fc7c476e
Thanks for bisecting this is very helpful! I am going to take a look now 😄
Your driver does not support
info: VK_EXT_custom_border_color
info: customBorderColors : 0
info: customBorderColorWithoutFormat : 0
Unfortunately, I removed a hack that we had from before I made and used this extension.
I think it should be supported in the latest Vulkan beta driver, not sure why this hasn't made it to mainline yet given it's had support since May...
Maybe it's something to do with your card generation :l
VK_EXT_custom_border_color?
Er, I'm stupid 🤦
I already found the solution 1 month ago with Crysis: Proton 5.0-9 doesn't support VK_EXT_custom_border_color...

I should have tested with Proton-GE and Proton-tkg (actually, it works with both!) before opening an issue, sorry 😬
(Proton 5.0-9 is old, I'm innocent!)
I can close it, thanks :)
