My biggest gripe with Qt is HiDPI support which was introduced just 6 months ago, so quite late. It feels cumbersome compared to HTML&#x2F;CSS which have native HiDPI support built-in for years. Also the implementation in HTML&#x2F;CSS is straightforward. You don&#x27;t need to think about it a second, it just works. Actually this is my number one feature of web tech, it&#x27;s HiDPI ready and websites and apps like Slack look always slick, crisp and clear, on any platform.<p>With Qt, just watch this 30 minutes presentation about Qt and HiDPI, while ok there are some parts which unnecessarily complicate matters: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=2XPpp4yD_M4" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=2XPpp4yD_M4</a>
