+# Phase 9 — Cursor Rendering
+
+---
+
+## Step 9.1 — Render the cursor in the compositor
+
+Since compositing may obscure the hardware cursor in certain
+configurations, render it ourselves:
+
+1. Call `XFixesGetCursorImage(dpy)` to get the current cursor bitmap
+   (ARGB pixel data, width, height, hotspot).
+2. Convert to a raylib `Texture2D`.
+3. Draw it at the pointer position each frame (query with
+   `XQueryPointer()`).
+4. Optionally call `XFixesHideCursor()` on the root and draw our own
+   cursor exclusively.
+
+Subscribe to cursor change notifications:
+
+```c
+XFixesSelectCursorInput(dpy, root, XFixesDisplayCursorNotifyMask);
+```
+
+Cache the cursor texture and only update it when an
+`XFixesCursorNotify` event fires (cursor shape changed — e.g., from
+arrow to text beam when hovering over `xterm`).
+
+**Verify:** The cursor is visible and correct when moving over composited
+windows. Cursor changes (e.g., text cursor in xterm, resize arrows at
+window edges) are reflected. No flickering or offset.
