Audio continued, and recording did not stop. Returning to the original Space restored the picture.</p> <p>I had already substantially improved QuickTime&rsquo;s offscreen freezes with <a href="../../../posts/gecko-adaptive-pulse-design/">Pulse</a> (in Chinese). This time, Safari&rsquo;s video content disappeared altogether. Adjusting the refresh frequency did not bring it back.</p>
