Panic in minimal Application with default settings

[ibaryshnikov]

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

Running the following app crashes

use iced::theme::Theme;
use iced::widget::text;
use iced::{Application, Command, Element, Settings};

struct App {}

#[derive(Debug, Clone)]
enum Message {}

impl Application for App {
    type Executor = iced::executor::Default;
    type Message = Message;
    type Theme = Theme;
    type Flags = ();

    fn new(_flags: ()) -> (App, Command<Message>) {
        (App {}, Command::none())
    }

    fn title(&self) -> String {
        "App".to_owned()
    }

    fn update(&mut self, _message: Message) -> Command<Message> {
        Command::none()
    }

    fn view(&self) -> Element<Message> {
        text("App").into()
    }
}

fn main() -> iced::Result {
    App::run(Settings::default())
}

Setting antialiasing to true fixes the issue

fn main() -> iced::Result {
    App::run(Settings {
        antialiasing: true,
        ..Settings::default()
    })
}

What is the expected behavior?

App runs with default settings

Version

crates.io release

Operating System

Linux

Do you have any log output?

I have the same problem

OS - Kubuntu 23.10
DE - KDE Plasma 5.27.8
Driver - NVIDIA 535
Platform - X11
ICED - 0.12

It could be problem with wgpu or vulkan because when I tried to run my up with WGPU_BACKEND=gl I run my app successfully.

I also tried to run my app on macos (metal) and everything was well

[1]    39911 IOT instruction (core dumped)  WGPU_BACKEND=vulkan cargo run --release

I thought that problem with vulkan driver but after re-installation by the next guide result was the same

[Harzu]

Today, I tested this bug in the GNOME DE using an Intel integrated GPU/Nvidia GPU (4070) on both Wayland and X11 platforms, and everything worked well. Therefore, I suspected that the problem might be with the Vulkan settings

I experimented with some settings, and the following environment variables fixed the problem.

VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json VK_LAYER_PATH=/usr/share/vulkan/explicit_layer.d cargo run --release

Assuming I'm an idiot... what file what i put this in?

These are just environment variables you can put them to bash script or Makefile and you can also put them to .profile/.bashrc/.zshrc or other session profile files but you need to understand that adding to profile files could affect something else.
