Yeah this is the reason most probably. After the UI update I had the exact same problem. After 2 days of search for solution I finally found it. When it tries to open with discrete GPU it just blinks and doesn’t open. I can only open it with integrated GPU. And you definitely have to use DRI_PRIME=1 argument for every game to open them with dGPU. It is kinda annoying but it’s only solution for now until Valve updates it.

I can only think of Waydroid if you are using Linux.

Debian not recommends testing for everyday using. You definetely have to look at the site. Afaik it is basically a bad version of unstable that gets slow updates and it is only for testing purposes.

Innovations are pretty rare in the desktop space but this looks like a really good innovation if implemented bug free.

Which still is a chrome frontend.
