Lagging GUI #69

Expected Behaviour

GUI is responsive

Observed Behaviour

There is a long lag time between interacting with GUI elements and them responding.

Environment

  • NixOS unstable
  • X11
  • LeftWM
  • NVIDIA 1060 6GB
  • Ryzen 2400G

Code

I'm using approach 4 to ensure egui renders into the correct color space.

Enable khr_swapchain_mutable_format.

let required_device_extensions = DeviceExtensions {
    khr_swapchain: true,
    khr_swapchain_mutable_format: true,
    ..DeviceExtensions::empty()
};

Create swapchain with SwapchainCreateFlags::MUTABLE_FORMAT.

let (swapchain, images) = Swapchain::new(
    vulkan_context.device.clone(),
    vulkan_context.surface.clone(),
    SwapchainCreateInfo {
        image_format: swapchain_format,
        image_view_formats: vec![swapchain_format, Format::R8G8B8A8_UNORM],
        min_image_count: surface_capabilities.min_image_count.max(2),
        image_extent: window_context.window.clone().inner_size().into(),
        image_usage: ImageUsage::COLOR_ATTACHMENT,
        composite_alpha: surface_capabilities
            .supported_composite_alpha
            .into_iter()
            .next()
            .unwrap(),
        flags: SwapchainCreateFlags::MUTABLE_FORMAT,
            ..Default::default()
    },
).expect("Failed to create Swapchain and/or Images");

Create Format::R8G8B8A8_UNORM image views of swapchain images.

let gui_image_views = images
    .iter()
    .map(|image| {
        ImageView::new(
            image.clone(),
            ImageViewCreateInfo {
                format: Format::R8G8B8A8_UNORM,
                ..ImageViewCreateInfo::from_image(image)
            },
        )
    })
    .map(Result::unwrap)
    .collect_vec();

Initialise Gui object with correct image view format.

let gui = Gui::new(
    event_loop,
    vulkan_context.surface.clone(),
    vulkan_context.queue.clone(),
    rendering_context.gui_image_views[0].format(),
    GuiConfig {
        is_overlay: true,
        ..Default::default()
    },
);

Create GUI elements in render loop.

WindowEvent::RedrawRequested => {
    self.gui.immediate_ui(|gui| {
        let ctx = gui.context();

        egui::TopBottomPanel::top("top_panel").show(&ctx, |ui| {
            ui.menu_button("File", |ui| {
                if ui.add(egui::Button::new("Import model")).clicked() {
                    ui.close_menu();
                }
            });
        });

        egui::SidePanel::left("left_panel").show(&ctx, |ui| {
            ui.heading("My egui Application");
            ui.label("Hello world");
        });
    });
    
    self.render(&mut frame_state);
}

Render scene and GUI then present.

let future = self
    .previous_frame_end
    .take()
    .unwrap()
    .join(acquire_future)
    .then_execute(self.vulkan_context.queue.clone(), command_buffer)
    .unwrap()
    .then_signal_fence_and_flush()
    .unwrap();

let gui_future = self.gui.draw_on_image(
    future,
    self.rendering_context.gui_image_views[image_index as usize].clone(),
);

let future = gui_future
    .then_swapchain_present(
        self.vulkan_context.queue.clone(),
        SwapchainPresentInfo::swapchain_image_index(
            self.rendering_context.swapchain.clone(),
            image_index,
        ),
    )
.then_signal_fence_and_flush();

This issue comes from my repo, vulkano-teapot. You can look at the whole source here if you need.

This issue does not happen in your examples, so something's wrong with my code somewhere.

This is a link to a flamegraph I generated using cargo-flamegraph

Thanks in advance for taking the time to look over this issue :)

I am noticing you are using my branch for your project. I am unable to reproduce the problem, even after running your project just after updating egui in your Cargo.toml to 0.27.
Maybe try running cargo update and doing the same to see if the issue is resolved in the newest egui release, or if that does not work try to run the examples in my repository if your have not done that and see if those also experience lag.
Would be happy to help you with your problem.

Thank you for the quick response.

Unfortunately none of these fixes have solved my problem.
The examples in your repository don't experience the same lag.

Also now I've updated the egui version to 0.27, I'm getting crashes after 1-4 frames of rendering. Here's the logs for that.

The application panicked (crashed).
Message:  called `Result::unwrap()` on an `Err` value: a validation error occurred

Thanks again for helping.

Following fix it for me on windows:

  1. Update egui: egui = "0.27.0" (does nothing with regards to the issue, but needed it for compilation)
  2. Remove the link stuff in build.rs (might be just a windows issue, also needed it for compilation)
  3. Remove the first .then_signal_fence_and_flush() leaving only the one just before match future.map_err(Validated::unwrap). This gets rid of the errors (resource in use).
  4. Add timeout to swapchain acquire (e.g. Duration::from_millis(10).

This was a quick debug, so didn't dig deep into further... e.g. resizing crashes the app entirely on my machine.

Maybe this helps a bit.

Thanks for the response.
Unfortunately none of these fixes have worked for me, I'm still experiencing the same crash. Commenting out gui.draw_on_image stops the crash so I'm pretty sure that is where the error originates.

Here's what I've done.

Updated egui version.

-egui = "0.26.0"
+egui = "0.27.0"

Added os specific targeting for build script.

 fn main() {
+    #[cfg(target_os = "linux")]
     println!(
         "cargo:rustc-link-search={}",
         std::env::var("NIX_LD_LIBRARY_PATH").unwrap_or_default()

Added in an aquire swapchain image timeout.

-        match acquire_next_image(self.rendering_context.swapchain.clone(), None)
+        match acquire_next_image(
+            self.rendering_context.swapchain.clone(),
+            Some(Duration::from_millis(10)),
+        )

Removed the first then_signal_fence_and_flush() call.

             .unwrap()
             .join(acquire_future)
             .then_execute(self.vulkan_context.queue.clone(), command_buffer)
-            .unwrap()
-            .then_signal_fence_and_flush()
             .unwrap();

Here's the full stacktrace.

The application panicked (crashed).
Message:  called `Result::unwrap()` on an `Err` value: a validation error occurred

    access to a resource has been denied (resource use: Some(ResourceUseRef { command_index: 0, command_name: "begin_render_pass", resource_in_command: FramebufferAttachment { index: 0 }, secondary_use_ref: None }), error: the resource is already in use, and there is no tracking of concurrent usages)
