Repro steps
Running anything which tries to use wgpu Vulkan, like:

cd examples && cargo run cube

The window starts and renders at least one frame, but becomes completely non-interactive (windows can't be interacted with or moved) and you receive a "hanging" prompt from GNOME:

Note that I think this might legitimately be a platform issue, however:

• I am unable to reproduce it with both vkcube (X11) and vkcube-wayland which reports and runs (see below).
• And winit examples run without issues.

> sudo dnf install vulkan-tools
> vkcube-wayland
Selected GPU 0: NVIDIA GeForce RTX 2080 Ti, type: DiscreteGpu

So wgpu is currently the lowest level of abstraction I've chased down.
