Streaming Far Cry 5 using Steam Play (Proton) does not stream the game, streaming stops working correctly.
In the steam logs I get "src/steamUI/gamestream/gamestreamsystem.cpp (867) : Assertion Failed: pState-m_nProcess == nProcess
I'm assuming it's because it's through uPlay Connect

Steps for reproducing this issue:

  1. Install Far Cry 5 using Proton 5.13-2 on Linux host
  2. On the client start the game to stream.
  3. Watch as uPlay connect launches the game.
  4. After the Far Cry 5 splash screen, the stream stops and the logs on the host get spammed with Assertion Failures.

The workaround for this is to configure wine to have a virtual desktop for the prefix but then if you're using a controller it will not get connected to the game correctly.

Is this specific to Proton 5.13?

Hi @Plagman,

This occurs with proton 5.0 as well and proton ge 5.9. I don't believe it is specific to the containerization of 5.13. I believe you saw my message in Discord as well with GloriousEggroll that it occurred with a few other games as well. I will note that streaming a native Linux game works OK but any Proton games it doesn't stream correctly. This has worked before though!

I'm having the same symptoms streaming Proton games from Ubuntu 20.04.1 LTS.

Proton + streaming does not seem to work for Skyrim. It freezes after a few frames with red connection icon, and there are assertion failures in the logs. Enabling a virtual desktop seemed to work (although it crashed later).

In comparison, streaming without Proton seems to work (Portal 2), and Proton without streaming seems to work (Skyrim).

I haven't played games in a long time, so I can't say if it's a regression or not.

I'm happy to provide logs if it would help.

Just to update this, I believe this issue only occurs on GNOME. I switched to KDE recently as I was having similar issues with the Mass Effect Legendary Edition trilogy (additionally the game would minimize when launched!) and I no longer have issues streaming even with other launchers. A bonus is that hooking into the game to use my PS4 controller over Remote Play works way better. I'm not sure what GNOME is doing, but it breaks things!

I can confirm the same thing. Streaming was fine on Ubuntu 18.04. After an upgrade to 20.04, I run into this issue streaming Skyrim SE. Switching to plasma by kde fixes the issue, and I can stream again.
I'd really like to uninstall KDE (kububtu-desktop) asap. Please.
