The pref gfx.webrender.software.unaccelerated-widget.allow may be used to allow software WebRender to be used with new windows/popups that have transparency on Windows. Otherwise they would fallback to basic layers. Similarly, the pref gfx.webrender.software.unaccelerated-widget.force may be used to force software WebRender for all windows that would fallback to basic layers.
