We have regulations here in Germany (EU wide even if I am not mistaken). The solar inverters used are required to shut off within I think 200ms of the 50hz grid power going down. The inverters sold here can’t output anything without grid power being detected on the AC output.

Why is everyone in this thread making assumptions and spreading fear instead of actually looking up how it works?

Yeah, especially the ones made by pharma companies that doctors hand out.

Have a look at Wayfire. It’s a Wayland compositor that implements a lot of the compiz effects/plugins. I recently found that but haven’t tried it myself as I don’t really care about wobbly windows and cubes as much as I did 15+ years ago when I first tried compiz as a teenager :D
