+# UI Redraw Logic (`needs_redraw` Flag)
+
+## Problem
+
+The main UI loop in `client/src/ui/handlers/ui.rs` uses `crossterm_event::poll` with a short timeout to remain responsive to both user input and asynchronous operations (like login results arriving via channels). However, calling `terminal.draw()` unconditionally in every loop iteration caused constant UI refreshes and high CPU usage, even when idle.
+
+## Solution
+
+A boolean flag, `needs_redraw`, was introduced in the main loop scope to control when the UI is actually redrawn.
+
+## Mechanism
+
+1.  **Initialization:** `needs_redraw` is initialized to `true` before the loop starts to ensure the initial UI state is drawn.
+2.  **Conditional Drawing:** The `terminal.draw(...)` call is wrapped in an `if needs_redraw { ... }` block.
+3.  **Flag Reset:** Immediately after a successful `terminal.draw(...)` call, `needs_redraw` is set back to `false`.
+4.  **Triggering Redraws:** The `needs_redraw` flag is explicitly set to `true` only when a redraw is actually required.
+
+## When `needs_redraw` Must Be Set to `true`
+
+To ensure the UI stays up-to-date without unnecessary refreshes, `needs_redraw = true;` **must** be set in the following situations:
+
+1.  **After Handling User Input:** When `crossterm_event::poll` returns `true`, indicating a keyboard/mouse event was received and processed by `event_handler.handle_event`.
+2.  **During Active Loading States:** If an asynchronous operation is in progress and a visual indicator (like a loading dialog) is active (e.g., checking `if app_state.ui.dialog.is_loading`). This keeps the loading state visible while waiting for the result.
+3.  **After Processing Async Results:** When the result of an asynchronous operation (e.g., received from an `mpsc::channel` like `login_result_receiver`) is processed and the application state is updated (e.g., dialog content changed, data updated).
+4.  **After Internal State Changes:** If any logic *outside* the direct event handling block modifies state that needs to be visually reflected (e.g., the position change logic loading new data into the form).
+
+## Rationale
+
+This approach balances UI responsiveness for asynchronous tasks and user input with CPU efficiency by avoiding redraws when the application state is static.
+
+## Maintenance Note
+
+When adding new asynchronous operations or internal logic that modifies UI-relevant state outside the main event handler, developers **must remember** to set `needs_redraw = true` at the appropriate point after the state change to ensure the UI updates correctly. Failure to do so can result in a stale UI.
