The demo on the Gio page is badly broken for me (Chrome 99 on Windows 10) - it’s mostly black, with what appears to be a text area in the middle with black text on black background. Triple clicking text doesn’t work. There’s no right click menu (as in native text areas) to show copy/paste/select all. There’s no visible scrollbar so it wasn’t obvious I could scroll down to see more UI controls. Overall it’s a terrible advertisement for the UI toolkit and seems typical of most immediate mode GUIs.
