Hi!

First, I should mention that the driver in general works very well and I have not encountered other problems with it.

I noticed however that vulkaninfo (from vulkan-tools) is not able to run. I think it is either related to Wayland or my prime configuration. I tried with both XWayland and Wayland.

```
  ~/dev/Vulkan-Tools/build master ❯ vulkaninfo

fish: “env DISPLAY= vulkaninfo” terminated by signal SIGSEGV (Address boundary error)
```

I then built vulkaninfo from source. The backtrace is not very helpful though, it crashes somewhere inside the NVIDIA egl libraries.

```

Any idea what this could be caused by? I provide core dumps if that is helpful.
