Running Nannou at all produces segfault, but WGPU works as expected

[shrinus]

Hello,

I am trying to get nannou to work on my arch linux computer and im having a bit of trouble

Currently, I am simply trying to produce a window with nannou.

``use nannou::prelude::*;

fn main() {
nannou::app(model).update(update).simple_window(view).run();
}

struct Model {}

fn model(_app: &App) -> Model {
Model {}
}

fn update(_app: &App, _model: &mut Model, _update: Update) {}

fn view(_app: &App, _model: &Model, frame: Frame) {
frame.clear(PURPLE);
}``

running with cargo run --release causes a seg fault.

running gdb target/release/nannou_project yeilds

Thread 1 "nannou_project" received signal SIGSEGV, Segmentation fault. 0x00007fffee410857 in ?? () from /usr/lib/libnvidia-glcore.so.560.35.03

I think? this is a problem caused by openGl, so i ran some WGPU examples.

these work as expected, and even recognize my discrete GPU and use vulkan.

I tried exporting the WGPU_BACKEND environment variable but nothing changes.

This is almost certainly a problem with your drivers or wgpu upstream. You may want to ensure that your drivers are up to date and that you are testing the wgpu examples against 0.17.1, which is our wgpu version on master.
