Agent Text Size resets when switching back to existing agent tabs

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The Text Size setting for agents is not applied consistently across agent chats. New chats correctly start with the configured text size, but when switching back to existing agent tabs, the text size for that chat appears to reset instead of preserving the configured value.

Steps to Reproduce

Cursor Settings → Agents → Text Size.

Set the Agent Text Size setting to a non-default value.

Start a new agent chat.

Confirm the new chat uses the configured text size.

Open or switch to another existing agent tab.

Switch back and forth between agent tabs.

Observe that the text size in some existing chats resets or no longer matches the configured setting.

Expected Behavior

All agent chats should consistently use the configured Text Size setting. Switching between new or existing agent tabs should not reset or change the displayed text size for any

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey @OsirisM!

Thanks for the feedback. A fix should ship in 3.9.

Hey @Colin !

It was fixed for a while with the 3.9 release, but now it’s back, and even worse this time, because the text size setting doesn’t even work anymore.

Looks like there’s a new report over at Agent text size doesn't get changed. Let’s continue over there.
