Typing delay in Copilot chat on Windows Edge

Rainer-3172 5

I’m experiencing a consistent typing delay in the Copilot chat input on Edge in Windows 11. The lag appears at the beginning of every line I type, and it gradually becomes worse the longer the session runs.

The issue occurs only on my new Surface Pro with Snapdragon, on the old Surface Pro with Intel there is no delay at all.

Edge on snapdragon sometimes stalls the ui thread right before the input compositor starts that’s the first‑keystroke lag ur seeing. intel skips that path entirely, so the delay never appears there.

Hi,

Just wanted to check, have you noticed this typing delay only in Microsoft Edge, or does it also happen when using Copilot in the standalone app or in other browsers like Chrome?

It is only in the Chat Window in Edge.

The delay sometimes is 20 sec. That is hardly usable.

I see the same on Intel x64 cpu. It started late 2025. It's slow to start the Copilot Chat in Edge, (Sidebar) and when it's loaded, it is also a long delay to activate the prompt field. totaly maybe 30-40 seconds.

I've been seeing similar input lag with Edge for the past 2 months (I don't use copilot). Incredibly frustrating.

Update Microsoft Edge to the latest version.

Test with Edge extensions disabled.

Clear Edge cache and site data for Copilot.

Disable Startup Boost and background extensions temporarily.

Try creating a new Edge profile and test Copilot there.

Try resetting your graphics driver? Windows + Shift + Ctrl + B is the keybind, normally clears up things like this for me
