What's Wrong?

Hey,

I upgraded yesterday from 2.0.58 to 2.1.3 yesterday. There were no problems. Today when I started my computer, I noticed lagg starting from 3rd prompt which just kept getting heavier and heavier, both when I was typing prompt and when claudecode was executing. I have cleared .claude to get rid of history, i checked LSP and disabled it, I installed clanged yesterday also and that was removed, still problems existed. So I downgraded back to 2.0.58 and now no problems.

I will also add, its only the terminal lagging at both 2.1.3 and 2.1.4 nothing else. I did go through as much as I could with claude to see where the problem would be, but couldn't find anything that would solve the issue. We checked CPU and nothing out of the ordinary. Im running it on ubuntun 24.04 and claudecode terminal, no IDE or anything else.

What Should Happen?

no lagg should happen
