DXKV on KDE fails but works on Gnome

I would really like to switch from Gnome to KDE, but DXVK with FFXIV holds me back. It works on Gnome 49 on Nvidia 590/kernel 6.18, but the same hardware on KDE 6.5 fails in DXVK’s call to vkCreateDevice.

```
D3D11InternalCreateDevice: Failed to create D3D11 device: Failed to create Vulkan device: VK_ERROR_INITIALIZATION_FAILED handle: 0x1780d58 device: 0
```

How can I troubleshoot this? Where do I file the bug report? I don’t understand the stack well enough. TYVM

I solved my own problem, sort of.

The problem goes away if I log in to a Gnome session first, log out, then log into a Plasma session. Running nvidia-smi first also fixes the issue. So this is probably an Nvidia driver bug? I posted about it on the Nvidia forums.
