Typing delay in ChatGPT Mac app (latest version, macOS Sonoma, 8GB RAM)

ChatGPT Bugs
1

I’m experiencing significant typing lag in the official ChatGPT Mac app, even when no other apps are open and memory pressure is moderate. I’m on the latest version of macOS (Sonoma) using a MacBook with 8 GB of RAM. The lag is only present in the app — not in the web version (which runs smoothly in Chrome).

I’ve already:

  • Closed all other apps (Safari, Mail, etc.)
  • Cleared Application Support, Containers, and Logs
  • Fully reinstalled the app
  • Monitored RAM & CPU in Activity Monitor (memory pressure yellow, swap used ~500MB)

The typing delay persists. It seems to be a rendering issue with Electron in low-RAM systems.
Please escalate this — it makes the app unusable.

Update:
I’ve now confirmed that the typing delay only occurs in context-heavy sessions, not in new chats.

In a fresh chat window, input is responsive and smooth. But in this long-running session — which includes images, code, long exchanges, and back-and-forth — typing becomes noticeably delayed, even though system resources are fine.

This strongly suggests the issue lies in how the app handles large session threads, possibly due to excessive DOM re-rendering or inefficient state handling in Electron/React.

This is important to distinguish from generic “app is slow on low-RAM” complaints. It’s a scaling issue inside the app’s input/render engine.

I’m experiencing the exact same issue, and I’m using the Safari web browser to access ChatGPT. I don’t recall having this problem before.

Same here, except I am having issues with the web version on Safari. I’m using a Mac Pro 16" (2019) with 64 GB RAM and an i9 processor. The issue persists even with all other apps closed, and low RAM & CPU usage. I can also confirm the issue is nonexistent in a fresh chat window, but impacts long-running sessions. It is virtually unusable in this state.

I have the exact same problem on the website (not the app).
