           <li>Fixes initial terminal window size being wrong at fractional DPR (e.g. 127×29 instead of configured 130×30 at 150% scaling on Wayland, #1858)</li>
+          <li>Fixes ~2s startup delay caused by synchronous Qt multimedia driver probing by deferring audio initialization to a background thread</li>
+          <li>Fixes initial font sizing at fractional DPR on Wayland by preferring screen DPR over window DPR</li>
           <li>Replaces abrupt cell blink toggle with configurable smooth pulse animation via blink_style profile setting (classic/smooth/linger)</li>
           <li>Adds configurable crossfade transition between primary and alternate screens via screen_transition and screen_transition_duration profile settings</li>

           <li>Adds snap-to-grid window resizing via WM size-increment hints (X11/macOS) and client-side snapping (Wayland, where xdg-shell has no size-increment hint)</li>
           <li>Adds hint mode for keyboard-driven selection of URLs, file paths, git hashes, and IP addresses with configurable actions (Copy, Open, Paste, Select), activatable via key binding or Vi normal mode (gh/gH)</li>
