What's Wrong?

Can't really reproduce, so treat this as just a signal that something is wrong. But, in this repository I have, I am getting constannt flickering in Powershell on windows 11 when using claude agents. Don't know what I did to trigger it, or if it's a bug with y'all. But it's bad man. If I was epileptic I'd be in serious trouble. Doesn't happen every time, only when I click on an agent. When I'm back in the main view, things are normal.

What Should Happen?

Should not flicker.

Steps to Reproduce

Open claude agents in a large repository with over 1000 directories and a crap ton of memories and skills. Can't give you my repo or machine, but that's pretty much what it is.
