- Fix wayland freezing.
- Windows: native MessageBoxW close-confirmation dialog when confirm-before-quit = true (default), mirroring macOS's applicationShouldTerminate NSAlert in rio-window/src/platform_impl/macos/app_delegate.rs. Replaces rio's in-window GPU-rendered confirmation modal on Windows. New EventLoopRunner.confirm_before_quit: Cell<bool> set via the same public EventLoop::set_confirm_before_quit that macOS already uses (cfg gate widened to any(target_os = "macos", target_os = "windows")). The WM_CLOSE handler in event_loop.rs checks the flag and vsync_state.window_count() <= 1 (only the last window prompts — matches macOS's app-wide quit semantics) and on confirm-No swallows the message so the window stays open. rioterm's WindowEvent::CloseRequested handler now follows the same fast path on Windows as on macOS — routes.remove(&window_id) + maybe-exit() — since the user already confirmed at the OS layer.
- Windows render loop now matches the macOS / CVDisplayLink model exactly: Window::request_redraw sets a per-window Arc<AtomicBool> dirty flag instead of immediately calling RedrawWindow(RDW_INTERNALPAINT). The DwmFlush worker thread (rio-window/src/platform_impl/windows/event_loop/vsync.rs) is the single source of frame timing — per composition cycle it iterates the window registry and, for each window where dirty || should_present_after_input (1 s post-input window, identical to macOS), calls RedrawWindow(.., RDW_INVALIDATE). Existing WM_PAINT → RedrawRequested path is unchanged. Plumbing: new vsync::VSyncSharedState (Arc<RwLock<HashMap<HWND, Arc<AtomicBool>>>> registry + Mutex<Instant> for last input) lives on ActiveEventLoop, threaded into WindowData and the Window struct so input handlers, request_redraw, and the worker all share it. Window::Drop unregisters before DESTROY_MSG_ID. Replaces the earlier "always invalidate per vsync" zed mirror — that approach worked but didn't compose with the app's own request_redraw, which made scroll feel locked to DWM tick. Now scroll-driven renders queue immediately into the next vsync (≤16 ms wait) and idle frames are skipped entirely. Net behaviour matches macOS one-to-one.
- Windows: window.blur = true now actually blurs (was a no-op stub). Implementation calls DwmSetWindowAttribute with DWMWA_SYSTEMBACKDROP_TYPE = DWMSBT_TRANSIENTWINDOW (Acrylic) when blur is on, DWMSBT_NONE when off — uses the existing set_system_backdrop plumbing in rio-window/src/platform_impl/windows/window.rs. Wired both at window creation (via attributes.blur in on_create) and at runtime via the cross-platform Window::set_blur. Requires Windows 11 22H2+; older builds silently no-op (matches the previous behaviour).
- Windows: vsync-driven render loop with 1-second post-input sustain (matches macOS / Linux / zed behaviour). All inside rio-window — frontends still just respond to RedrawRequested. New worker thread (platform_impl/windows/event_loop/vsync.rs) calls DwmFlush() per composition cycle; when DWM is disabled, the monitor is asleep, or the call returns under the 1 ms threshold (RDP / occluded), it falls back to thread::sleep at the queried DwmGetCompositionTimingInfo.qpcRefreshPeriod interval, with a rateRefresh numerator/denominator fallback for spuriously low values and a 16.6 ms (60 Hz) default if both queries fail. Same heuristic zed uses in gpui_windows/src/vsync.rs. Each tick PostMessageW's a registered custom message (Winit::VsyncTick) to the existing thread_msg_target; the handler in thread_event_target_callback enumerates thread windows via EnumThreadWindows, filters with IsWindowVisible, and posts RedrawWindow(hwnd, RDW_INTERNALPAINT) per visible window so the existing WM_PAINT path emits RedrawRequested unchanged. The fan-out is gated on a new EventLoopRunner.should_present_after_input() (1 s window after the last input event) — same field/method names as the macOS / Wayland / X11 implementations. mark_input_received is hooked into public_window_callback_inner for WM_KEY{DOWN,UP},

Note: v0.2.21 introduces a new rendering architecture per terminal damage system, and it may contain bugs. Any issue please report 🙏
Changelog
- Breaking: navigation.use-current-directory has been renamed to navigation.current-working-directory.
Performance Optimizations
- Major: Implemented efficient CVDisplayLink-based VSync synchronization for macOS
- Perfect frame timing aligned with display hardware refresh cycles
- Eliminates screen tearing and stuttering through hardware VSync synchronization
- Adaptive refresh rate support: automatically handles 60Hz, 120Hz, ProMotion displays
- Multi-display support: adapts when windows move between displays with different refresh rates
- Grand Central Dispatch (GCD) integration for thread-safe cross-thread communication
- Smart rendering: Only renders when content actually changes using dirty flag system
- Power efficient: skips unnecessary redraws when content is static, reducing CPU usage
- Professional rendering quality with smooth, tear-free visual updates
- CVDisplayLink runs on dedicated background thread, never blocking UI operations
- macOS VSync Optimization: Disabled redundant software-based vsync calculations on macOS
- CVDisplayLink already provides hardware-synchronized VSync timing
- Eliminates unnecessary frame timing calculations and monitor refresh rate queries
- Reduces CPU overhead and improves rendering performance
- Software vsync logic remains active on other platforms for compatibility
- Major: Implemented a new text run caching system replacing line-based caching
- Up to 96% reduction in text shaping overhead for repeated content
- Individual text runs (words, operators, keywords) cached and reused across frames
- 256-bucket hash table with LRU eviction for optimal memory usage
- Cache Warming: Pre-populate cache with 100+ common terminal patterns on startup
- Programming keywords: const, let, function, class, import, export, etc.
- Indentation patterns: 4/8/12/16 spaces, single/double/triple tabs
- Shell commands: ls, cd, git, npm, cargo, sudo, etc.
- Operators & punctuation: =, ==, =>, ();, {}, [], etc.
- File extensions: .js, .ts, .rs, .py, .json, .md, etc.
- Error/log patterns: Error:, [INFO], FAILED, SUCCESS, etc.
- Immediate cache hits eliminate cold start shaping delays
- SIMD-Optimized Whitespace Detection: Multi-tier optimization for indentation processing
- AVX2: 32 bytes per instruction (x86-64 with AVX2 support)
- SSE2: 16 bytes per instruction (x86-64 with SSE2 support)
- NEON: 16 bytes per instruction (ARM64/aarch64)
- Optimized scalar: 8-byte chunks (universal fallback)
- Up to 32x performance improvement for long indentation sequences
- Critical for Python, nested JavaScript/TypeScript, YAML, and heavily indented code
- Memory Pool for Vertices: High-performance vertex buffer pooling system
- Size-categorized pools: Small (64), Medium (256), Large (1024), XLarge (4096) vertices
- Zero allocation overhead through buffer reuse across frames
- LRU management with automatic cleanup when pools reach capacity
- Thread-safe concurrent access with performance monitoring
- Eliminates GC pressure and improves frame rate consistency
- Background Font Operations: Non-blocking font management
- Font data release and cleanup in dedicated background thread
- System font scanning and preloading without blocking main thread
- Prevents frame rate drops during font operations
- Occlusion-Based Rendering: Skip rendering for occluded windows/tabs
- Automatically detects when windows are completely hidden by other windows
- Skips rendering for occluded windows to save GPU resources and improve performance
- Renders one frame when window becomes visible again to ensure display is updated
- Configurable via [renderer] disable-occluded-render = true (enabled by default)
- Significantly improves performance when running multiple tabs or windows
Other Improvements
- Optimize the character cluster cache for wide space characters.
- New font atlas, more efficient.
- Imple

0.2.20
- Performance: Implemented SIMD-accelerated UTF-8 validation throughout Rio terminal using the simdutf8 crate.
- Architecture support: AVX2/SSE4.2 (x86-64), NEON (ARM64), SIMD128 (WASM)
- Automatic optimization: Runtime detection selects fastest implementation available
- Support for XTGETTCAP (XTerm Get Termcap) escape sequence for querying terminal capabilities.
- Font library is now under a RWLock instead of Mutex to allow multiple tabs readings same font data.
- Fix: crash on openSUSE Tumbleweed #1160.

Example:
[shell]
# default (in this case will be used only on MacOS)
program = "/bin/fish"
args = ["--login"]

[platform]
# Microsoft Windows overwrite
windows.shell.program = "pwsh"
windows.shell.args = ["-l"]

# Linux overwrite
linux.shell.program = "tmux"
linux.shell.args = ["new-session", "-c", "/var/www"]

- Fix: Grey triangle in the titlebar #778
- Update window title straight away (#779 by @hunger)
