Hey, I can see the screenshot. Two chat inputs are stacked in the right panel. We’ve seen a similar bug before and it was fixed, so this could be a regression in 3.5.17.
A couple questions and a quick workaround:
Try closing one of the duplicates: right click the second chat tab and pick Close. Or open the Command Palette with Cmd+Shift+P and run View: Reset View Locations.
Do you remember what you did right before the second input appeared? For example, did you use Cmd+L, drag a chat tab, or open a split view?
After resetting the layout, does it come back on its own, or only after specific actions?
If you can reproduce it, share the steps and I’ll pass it to the devs as a possible regression.
