# Objective Fixes https://github.com/bevyengine/bevy/issues/11157. ## Solution Stop using `BackgroundColor` as a color tint for `UiImage`. Add a `UiImage::color` field for color tint instead. Allow a UI node to simultaneously include a solid-color background and an image, with the image rendered on top of the background (this is already how it works for e.g. text).  --- ## Changelog - The `BackgroundColor` component now renders a solid-color background behind `UiImage` instead of tinting its color. - Removed `BackgroundColor` from `ImageBundle`, `AtlasImageBundle`, and `ButtonBundle`. - Added `UiImage::color`. - Expanded `RenderUiSystem` variants. - Renamed `bevy_ui::extract_text_uinodes` to `extract_uinodes_text` for consistency. ## Migration Guide - `BackgroundColor` no longer tints the color of UI images. Use `UiImage::color` for that instead. - For solid color buttons, replace `ButtonBundle { background_color: my_color.into(), ... }` with `ButtonBundle { image: UiImage::default().with_color(my_color), ... }`, and update button interaction systems to use `UiImage::color` instead of `BackgroundColor` as well. - `bevy_ui::RenderUiSystem::ExtractNode` has been split into `ExtractBackgrounds`, `ExtractImages`, `ExtractBorders`, and `ExtractText`. - `bevy_ui::extract_uinodes` has been split into `bevy_ui::extract_uinode_background_colors` and `bevy_ui::extract_uinode_images`. - `bevy_ui::extract_text_uinodes` has been renamed to `extract_uinode_text`. |

Stress tests
These examples are used to stress test Bevy's performance in various ways. These should be run with the "stress-test" profile to accurately represent performance in production, otherwise they will run in cargo's default "dev" profile which is very slow.
Example Command
cargo run --profile stress-test --example <EXAMPLE>
