I really don’t know what you are talking about. I’m using it on Linux and it runs great. Comparing Signal to Discord, as both are electron apps, Discord is pure shit, Signal works really well. It takes a couple seconds to load but it’s still faster than Discord for me.

I would prefer if it would use other cross-platform framework like Flutter or Qt, but you can’t have everything. It’s better to have electron app, than don’t havy any.

I wouldn’t use Proton to play this game as it had more problems on my machine than native Linux version. Try using Steam Linux Runtime in Steam’s compatibility tab.
