Relevant logs or output

The title bar has changed a lot since v1.38.1: the desktop now runs on Electron, and the top bar spans the full window width with the window controls placed on it. Could you check on v1.39.0 whether the minimize, maximize and close buttons still show a different background? If they do, please attach a screenshot and say which theme you use and whether the right-side workspace panel is open.
