@SkyLeite, please could you capture the information from Help -> Steam Runtime Diagnostics? (This used to be in Help -> System Information, but newer versions of Steam have moved it.)

It would also be useful if you can try the `client_beta` branch of "Steam Linux Runtime - sniper". It's the same procedure as [opting in to the beta branch of...

Another useful thing to try would be launching a different title that uses sniper. At the moment there are not very many, so that basically means [Endless Sky](https://store.steampowered.com/app/404410/Endless_Sky/) or [Retroarch](https://store.steampowered.com/app/1118310/RetroArch/),...

@kisak-valve can convert steam-runtime bugs into Dota-2 bugs, so there's no need to close and reopen a bug. This might be specific to some particular GPUs or Vulkan drivers or...

@elicia4: If you are not using the same operating system and @SkyLeite's workaround does not work for you, then you are probably seeing a similar symptom for a different reason....

> However, it needs to play audio, and the current dependency makes use of `libgstreamer1.0-dev` and `libgstreamer-plugins-base1.0-dev` to run, which are typically available in host systems (but not always). The...

Flatpak is not really designed for this use-case: it is designed for GUI apps, analogous to what the term means on (for example) Android or iOS, so implementing the proposed...
