What app do you use or recommend for sharing you location with family and friends? Google Maps can do this, but I'm looking for a non-Google option. Something in the OpenStreetMaps space would be the best. Telegram can also do it, but Telegram's feature is more optimized for short-term sharing, not continuous sharing.
Probably yes. Vulkan is everywhere now. For example I use a lot of Gamescope to play (upscale) older games and it uses Vulkan.
