Description

What version of the Codex App are you using (From “About Codex” dialog)?

Version 26.825.51511

What subscription do you have?

x20

What platform is your computer?

No response

What issue are you seeing?

Huge lag spike on my computer (not just Codex) when using @ character, and my laptop immediately gets significantly hotter and I see memory gets maxed out. Maybe the search is inefficient and it over-recruits resources?

What steps can reproduce the bug?

Type @ on a thread - though I found that sometimes it works fine for some reason

What is the expected behavior?

Research direction

Start by reproducing the issue in Codex App version 26.825.51511: type @ on a thread and observe system lag, heat, memory use, and whether the behavior is intermittent. Trace the @-triggered search or resource usage to identify the regression; done means typing @ no longer causes a significant lag spike or resource exhaustion.
