# Objective I am building an [app](https://github.com/nolight132/sonora) with GPUI, and the current animation throttling implementation does not quite meet its requirements. I needed the window to stay at a smooth framerate when unfocused to display lyrics, which was not possible at the time without modifying GPUI’s frame scheduling behavior. I understand that this is not a problem for Zed, but I believe making this behavior a field in `WindowOptions` could be beneficial for other programs going forward. ## Solution Added a field to `WindowOptions` struct which controls the minimum interval between animation frames while the window is inactive (documented). Kept the default value GPUI currently uses. ## Testing - Ran `gpui/src/examples/animation.rs` with different presets - works as expected. Zed compiles. One thing worth noting: this setting does not guarantee the window refreshes at this exact interval, as frames are still paced by the compositor. For granular FPS control, a helper function is needed. I have decided to keep it simple and use the existing logic. - Tested on NixOS x86_64, Niri. ## Self-Review Checklist: - [x] I've reviewed my own diff for quality, security, and reliability - [x] Unsafe blocks (if any) have justifying comments - [x] The content adheres to Zed's UI standards ([UX/UI](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist) and [icon](https://github.com/zed-industries/zed/blob/main/crates/icons/README.md) guidelines) - [ ] Tests cover the new/changed behavior (the default didn't change, tests still pass) - [x] Performance impact has been considered and is acceptable (no performance impact unless explicitly set) ## Showcase Before (unfocused): <img width="1280" height="802" alt="image" src="https://github.com/user-attachments/assets/e3302c1d-4f4a-4503-96a2-0bf24e28096c" /> After (unfocused with `inactive_frame_interval` set to 16ms): <img width="1450" height="972" alt="image" src="https://github.com/user-attachments/assets/1183adf1-2da1-42d5-8e97-f4ad7a31b783" /> --- Release Notes: - Added `WindowOptions::inactive_frame_interval` for configuring animation frame throttling on inactive GPUI windows.
