This is a known memory/performance issue with the GitHub Mobile app when rendering very large README files. The app's rendering engine struggles with large DOM elements.

Workarounds:

1. Split your README - Break a very large README into smaller sections using HTML summary/details or links to separate markdown files in the repository
2. Update mobile app - Ensure you're on the latest version (current: 1.249.1+). Check your app store for updates
3. Use lazy loading - If you control the repository, consider using collapsible sections:

   <details>
   <summary>Click to expand section</summary>
   Large content here
   </details>

4. Alternative access - Use the web version on mobile browser as a temporary workaround

For GitHub team: This is a legitimate performance regression that should be escalated to the Mobile app team for optimization. The rendering of large markdown documents needs memory/performance improvements.
