How to fix slow scrolling in ChatGPT
Updated May 27, 2026
Quick answer
Slow scrolling in a long ChatGPT conversation is caused by the browser rendering every message in the page at once. As the DOM grows, each scroll event triggers layout and paint work across the whole list. Refreshing the page or closing other tabs buys a few minutes of relief before the stutter returns. Speed Booster fixes the rendering by keeping only the messages near your viewport in the page. Off-screen messages are removed from the DOM and restored on demand as you scroll.
Scroll stutter in ChatGPT is not subtle once a thread gets long. The page hitches, frame rate drops, and scrolling through the conversation feels like dragging. This is not a network issue. The messages are already loaded. The browser is the bottleneck, and the fix is reducing how much it has to render at any moment.
- 1
Confirm the issue is scroll-related, not typing-related
Scroll through a long ChatGPT thread and note whether the stutter happens during scrolling, during typing in the composer, or both. Speed Booster addresses both, but confirming which is slower helps you know what to look for after installing.

Install GPT Master to enable Speed Booster
Install the extension and Speed Booster runs automatically with no per-conversation setup. Open the long conversation where you noticed the slow scroll and test it. Scrolling should feel noticeably smoother.

Switch to Turbo mode for threads over a few hundred messages
Upgrade to GPT Master Pro for Turbo mode if Standard improves but does not fully solve the scroll performance on a very long thread. Turbo handles the highest message counts.

Frequently asked questions
- Does Speed Booster affect how messages look while scrolling?
- Messages load smoothly as they enter the viewport. There is no visible pop-in during normal scrolling. The transition is fast enough that the visual experience matches a natively rendered list.
- Will Speed Booster fix scroll lag in ChatGPT Projects and Custom GPTs?
- Yes. Speed Booster applies anywhere a ChatGPT conversation is open inside chatgpt.com, including Projects and Custom GPTs.
- My scroll is slow even in short ChatGPT threads. Does Speed Booster help?
- Speed Booster targets rendering overhead from long message lists. If a short thread is slow, the cause is more likely a browser performance issue unrelated to the DOM size. Check extensions, available memory, and graphics settings first.
