We are developing UI in slint-rs for our product. Our eventiual target is IoT devices (cyber defense) though we are starting with desktops. We are a young startup and our experience is very limited in UI space so please take all of it with a pinch of salt.
One of our intern got the UI working with Slint in a few days and since then we didn't feel a strong need to move away from it. We found a few missing features: it was not possible to tell if a Windows is hidden or not. We ended up sending a few patches.
So far our experience has been pretty good with slint-ui. We are not tested the UI on OSX and Linux yet, only windows. On AWS machines with Windows server, the UI fails to launch sometimes because of some missing GL libraries. Also note the licensing of Slint-UI https://github.com/slint-ui/slint/discussions/379.
