The GLES backend for Zed is crashing for me under both X11 and Wayland. This has been occuring since at least zed-industries/zed#13114 but has probably been present for much longer. This occurs whenever you resize the window (if doing the hello_world example, which has been there the whole time) or at startup if running Zed (though I don't think this has always been the case).

This is what gets printed out:

Zed works fine when disabling transparency:

Interesting, so these attributes are incorrect

attributes.push(egl::TRANSPARENT_TYPE);
attributes.push(egl::TRANSPARENT_RGB);

Just tried building Zed with the changes in #145 and it still crashes with the same error. Can this be reopened?

If you can build, it would help if you could narrow it down a bit by playing with this section

let mut attributes = vec![
            egl::RENDER_BUFFER,
            // We don't want any of the buffering done by the driver, because we
            // manage a swapchain on our side.
            // Some drivers just fail on surface creation seeing `EGL_SINGLE_BUFFER`.
            if cfg!(any(target_os = "android", target_os = "macos", windows)) {
                egl::BACK_BUFFER
            } else {
                egl::SINGLE_BUFFER
            },
        ];

        //TODO: detect if linear color space is supported
        match inner.egl.srgb_kind {
            SrgbFrameBufferKind::None => {}
            SrgbFrameBufferKind::Core | SrgbFrameBufferKind::Khr => {
                attributes.push(egl::GL_COLORSPACE);
                attributes.push(egl::GL_COLORSPACE_SRGB);
            }
        }

Found this note in the documentation:

EGL_BAD_ALLOC is generated if there is already an EGLSurface associated with native_window (as a result of a previous eglCreatePlatformWindowSurface call).

So I tried to add this hotfix:

if let Some(s) = inner.swapchain.take() {
    inner.egl.instance.destroy_surface(inner.egl.display, s.surface).unwrap();
}

This helped on my PC, Zed no longer crashes.

So I guess the proper fix of this issue is implementing //TODO: remove old surface

(however, Zed uses llvmpipe instead of hardware rendering for some reason... but this is a topic for another issue)

(there is another crash BadDisplay at egl.rs:92 after closing one of multiple Zed windows, but this is probably also a topic for another issue)

Awesome, do you want to submit a PR for this, @andreymal ?

No, I actually don't know any GL
