Rounded corners are a bit rough

As you can see from the screenshot, the rounded corners are a bit rough.

Yeah, that's not a problem with the code. The code simply "cuts" the window corner, so drawing a little border around it like the terminal does would be quite the hack.

Does using the border-width property help? you can access it via mutter_settings or dconf-editor

Try to make clipping on each edge 1px in mutter_settings, this will effectively remove the original borders provided by your GTK Theme. If you still want the border, set the border width in mutter_settings

Honestly, mutter should ship with those borders clipped (I personally have them at 1,1,2,1). Solves what some may think is a bug, and it looks nicer without those horrendous default 1px solid black borders on otherwise light-themed apps in Gnome. But I think the visuals speak for themselves:

Is it possible to add a feature to render additional borders on windows?
