@Lydie Not like on Windows. The UI supports 1x and 2x scales for low and high-resolution displays respectively. Beyond that you can render the display in higher resolution than the panel and then scale it down to achieve smaller UI, but at the cost of some image quality.
This has saved the entire ecosystem from a ton of headache, because nothing on the screen ever appears in the wrong size relative to other elements, which is common on Windows in my experience.
