not sure if same reason but window resize feels better in claude than codex.

on my m1, claude is noticeably slower when starting, but it feels ok after that.

I had a nasty slow claude code startup time at one point something like 8s, a clean install sorts it all out. Back up your mcp config and skills and you're good.

That sounds like poor engineering on Anthropic's part. Good software doesn't slow down over time like that.
