  "textContent": "Thanks for acknowledging the issue.\n\nHowever this should probably be treated as more than a minor UX\nfriction.\n\nChatGPT is fundamentally a productivity tool. UI latency directly\nreduces user productivity, especially during typing where any lag\nbreaks flow.\n\nFrom the outside it appears that large conversations cause the UI\nto render and maintain an increasingly large DOM tree, which leads\nto expensive layout recalculations and input lag over time.\n\nVirtualized list rendering (windowing) is a standard solution for\nlong lists in modern UI architectures and is widely used to keep UI\nlatency constant regardless of list size.\n\nBecause this issue directly affects typing responsiveness — one of\nthe most critical interaction loops in the product — leaving it\nunresolved creates a contradiction between the product’s goal\n(productivity) and the actual user experience.\n\nFor that reason this likely deserves treatment as a priority\nperformance defect rather than just a UX improvement.",
