Two issues fixed: 1. Added mouse event handlers to divider element - on_mouse_move to track drag position - on_mouse_up to end drag Previously events were only on parent, but mouse moves off divider during drag 2. Fixed calculate_new_ratios ratio calculation - Was incorrectly assuming ratios sum to 1.0 (visible_ratio_total = 1.0 - hidden) - Actually ratios are [1.0, 2.0, 1.0] summing to 4.0 - Now correctly sums visible ratios for proper width calculation Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The custom cursor rendering was causing layout problems, particularly with TUI applications like Claude Code where the cursor appeared in the wrong position (below the status line) and caused the UI to shift. Changes: - Add display_offset, line_offset, viewport_rows to TerminalContentSnapshot - Improve build_lines_from_content to handle non-zero starting line indices - Disable custom cursor rendering (TODO: implement proper cursor following Zed's terminal_element.rs approach) The terminal content from alacritty already handles cursor visualization through cell attributes, so disabling the custom cursor overlay provides a better user experience until proper cursor rendering is implemented.

Following Zed's terminal_element.rs patterns: - Add DisplayCursor struct with from(cursor_point, display_offset) - Use BTreeMap for line grouping with enumerated screen positions - Add shape_cursor function with viewport bounds checking - Re-enable cursor rendering with proper coordinate transformation The key insight from Zed: cursor.line.0 + display_offset transforms Alacritty's coordinate system (negative scrollback) into screen coordinates (0, 1, 2...).

The custom cursor was rendering in the wrong position (below the status bar in TUI apps like Claude Code). Disabling it makes the terminal more usable while we investigate the root cause. Investigation findings: - Coordinate transformation (line.0 + display_offset) appears correct - Content and cursor use same coordinate system - Spacing issue (UI shifted 1 line) exists independently of cursor - Root cause still under investigation Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
