Wgpu + winit surface error on Wayland

Rajakenhd · November 6, 2024, 9:27pm

So I want to work with wgpu + winit for a project and I kept getting a weird Error Message, so I've tried the learn-wgpu examples and encountered the same error
wp_linux_drm_syncobj_manager_v1#55: error 0: Surface already has a syncobj attached

The compositor I'm using is Hyprland, but that is not the cause, since Gnome Wayland showed the same problem, but when I tried xorg, it worked, but I want to use Wayland, but haven't really found any solution for that

if you want the code of one example:

github.com

sotrh/learn-wgpu/blob/master/code/beginner/tutorial2-surface/src/lib.rs

use std::iter;

use winit::{
    event::*,
    event_loop::EventLoop,
    keyboard::{KeyCode, PhysicalKey},
    window::{Window, WindowBuilder},
};

#[cfg(target_arch = "wasm32")]
use wasm_bindgen::prelude::*;

struct State<'a> {
    surface: wgpu::Surface<'a>,
    device: wgpu::Device,
    queue: wgpu::Queue,
    config: wgpu::SurfaceConfiguration,
    size: winit::dpi::PhysicalSize<u32>,
    // The window must be declared after the surface so
    // it gets dropped after it as the surface contains

This file has been truncated. show original

But the problem seems to be a general thing with wayland / wgpu
please, if anyone can help.
Any advice appreciated.

Ok, Edit: I tracked it down to the VULKAN Backend
The Backend was set to Primary and seemingly defaulted to vulkan.
When selecting GL as backend it actually works

So I still would like help with fixing the Vulkan problem, but if anyone comes across this with a similar problem
Stopgap solution
change the instance backend from Vulkan to GL or try the others, depending on your system

This appears to be a known issue: Vulkan surface creation fails on wayland · Issue #6320 · gfx-rs/wgpu · GitHub

And this issue was closed as a duplicate, but has what looks like exactly the same error message: Program not running and just crashing. · Issue #6355 · gfx-rs/wgpu · GitHub

Looks like the same problem as Vulkan backend in renderdoc with wayland · Issue #3889 · gfx-rs/wgpu · GitHub from back in June 2023. That's still open. Did WGPU ever work on Wayland other than in old OpenGL mode?
