Hello Albert, Here is an archive containing a test project along with a longer video of my reproduction: https://www.icloud.com/iclouddrive/0cei7q8T4jFu17bCxjbq-RoUg#XcodeLongFlickeringDemo+Project Thanks

Hello, Yes, I’m also affected. I’m using Version 26.2 (17C48) from the Developer site and running on Tahoe 26.1. My company has set up a system with LiteLLM to use multiple models. The integration works perfectly, but as soon as I close Xcode or reboot the computer, I lose the configuration and my history.
