FWIW, while this sounds about right for `icon`ified frames, for those frames that are marked as actually invisible, I think we should try and keep them as invisible as possible. IOW if they appear as preview/thumbnails somewhere it should itself be considered as a bug (either in our code or in the compositing manager or ...). Keeping the preview's appearance up-to-date is wasted efforts in this respect. Stefan PS: In case you need to see concrete uses of invisible frames, you can find one in `server.el` and another in GNU ELPA's `xclip.el`. There are probably others, but these are the one I know of because I coded them :-)
