OpenGL seems to work fine here

I'm curious here, does this happen right on startup or after some time of usage?

[flukejones]

On startup

[tronical]

Darn. Ok, after commit b00752514c0bfc24b820dae56d18d9d271bea260 removing "renderer-skia-vulkan" in your Cargo.toml should be a way to avoid this code path. It sucks that we can't handle this panic :(
