Turn off vim mode if you use it. There is some kind of bug with it I found it basically unusable. With vim mode off it sort of works ok. Only breaks occasionally.

But hey coding is a solved problem.

That's interesting - I just fixed my terminals rendering by having Claude build a test harness that used tmux as an oracle, and one of the programs it fixed the rendering of by reading out the tmux pane was Claude Code itself...

Is this a new regression for others? I feel like I used it in a tmux setup without issues for 6+ months and only recently am I forced to Ctrl+L or resize the window constantly.
