Hey, thanks for the detailed report and the screenshot. I can see the text is being typed in reverse, and the caret jumps to the start of the line on every character.
This is a known issue with the detached or pop-out chat window. The Lexical-based input loses its focus context when the tab is moved into a separate window. We’re already tracking it, but I can’t share an ETA for a fix yet.
As a temporary workaround, you can try disabling hardware acceleration via the Command Palette with “Disable Hardware Acceleration”, or via Preferences. Some users report that typing works normally in the detached window after that. No guarantees, but it’s worth a try. Until this is fixed, the most reliable option is to keep chat in the main window.
I’ll merge this thread into the main discussion so everything stays in one place: Editor in a new window, zoomed in, typing from right to left. Subscribe there to get updates on the fix.
