Describe the bug

When I run the example problem from the eframe docs one of the following 2 errors come out (interchangeably):

Actual output:

os error 32 happens more often

To Reproduce Steps to reproduce the behavior:

I suspect this is due to running this on WSL, the code that reproduces this error is the example in the eframe docs, shown here:

main.rs

use eframe::egui;

fn main() {
    let native_options = eframe::NativeOptions::default();
    eframe::run_native(
        "My egui App",
        native_options,
        Box::new(|cc| Ok(Box::new(MyEguiApp::new(cc)))),
    ).unwrap();
}

#[derive(Default)]
struct MyEguiApp {}

impl MyEguiApp {
    fn new(cc: &eframe::CreationContext<'_>) -> Self {
        // Customize egui here with cc.egui_ctx.set_fonts and cc.egui_ctx.set_visuals.
        // Restore app state using cc.storage (requires the "persistence" feature).
        // Use the cc.gl (a glow::Context) to create graphics shaders and buffers that you can use
        // for e.g. egui::PaintCallback.
        Self::default()
    }
}

impl eframe::App for MyEguiApp {
    fn update(&mut self, ctx: &egui::Context, frame: &mut eframe::Frame) {
        egui::CentralPanel::default().show(ctx, |ui| {
            ui.heading("Hello World!");
        });
    }
}

Cargo.toml with the patched version, the error remains even in 0.28 or 0.28.1 w/o the patch

[package]
name = "eframe_egui_bug"
version = "0.1.0"
edition = "2021"


[dependencies]

eframe= "0.28.1"
[patch.crates-io]
eframe = { git = "https://github.com/emilk/egui", branch = "master" }

[workspace]
resolver = "2"

run $ RUST_BACKTRACE=1 cargo run

Expected behavior

A window with Hello World on it. Eframe 0.23 worked on a previous project of mine but this version here no longer works.

Screenshots

For a split second the window appears

I solved this issue by moving the file over to the windows system, installing Rust via powershell (though im unsure if this is necessary), and then running via cargo as normal.

JusticeBaum avatar Oct 14 '24 22:10 JusticeBaum

The error happens in the WSL, not on the actual windows system. Cargo, the source, and all dependencies are contained in the WSL not on windows, and the program is run on the WSL not windows itself.

  • Info: the WSL installation is in Windows 10

ravatex avatar Oct 15 '24 08:10 ravatex

Yes but within WSL navigating over to the mounted Windows file system cd /mnt/c/Users/... and containing the project there solved the issue on my system; Other alternatives I've seen for this issue have been setting up X forwarding between WSL and Windows or building for Windows when compiling your project. The issue stems from linux and windows graphic drivers not playing nice

JusticeBaum avatar Oct 15 '24 15:10 JusticeBaum

I am having same issue. For me it also mentions the clipboard. Tried updating WSL (using Ubuntu btw), as well as all apt packages but to no avail.

Btw, this happens when I use eframe::run_native (doesn't matter what example I try), not when using eframe::run_simple_native.

A workaround for me was: After application launch the application window does not have focus. Focus a window from a different application by clicking in in the task bar or directly. Then focus your launched application.

Of course this is nothing for production but it does help for dev. Maybe this is also a hint for the root-cause ?

AndreasFuchsTPM avatar Apr 04 '25 11:04 AndreasFuchsTPM

you can run the app with "./YourApp > /dev/null". It worked for me.

I have this problem starting with egui = 0.25. With egui = 0.24 I do not run into this error.

michaelmdresser avatar Jul 17 '25 05:07 michaelmdresser

when you are making the native options for the frame

let native_options = eframe::NativeOptions {
        viewport : egui::ViewportBuilder::default().with_inner_size([640.0,320.0]).with_resizable(true),
        ..Default::default()
};

also mention the viewport with your desired size.

partg952 avatar Jul 27 '25 18:07 partg952

i may have solved it..

when you are making the native options for the frame

let native_options = eframe::NativeOptions {
        viewport : egui::ViewportBuilder::default().with_inner_size([640.0,320.0]).with_resizable(true),
        ..Default::default()
};

also mention the viewport with your desired size.

don't think that solved anything, but i tried it too and it worked somehow. i would like to mention that if i give it the inner size in a vec form, it results in the same error:

let native_options = eframe::NativeOptions {
        viewport: egui::ViewportBuilder::default()
            .with_inner_size(egui::vec2(800.0, 600.0))
            .with_resizable(true),
        ..Default::default()
    };
