Please describe your issue in as much detail as possible:

When playing Warframe via Steam which has been installed via Flatpak I get the following log spam:

Mar 16 16:03:16 debian steam[6391]: Fossilize WARN: Graphics pipeline handle 0x00007f23586f0fb0 is not registered.
Mar 16 16:03:16 debian steam[6391]: It has either not been recorded, or it failed to be recorded earlier (which is expected if application uses an extension that is not recognized by Fossilize).

There's so many messages emitted to the journal that it seems to slow down the game and cause it to stall. I've also posted about this bug to the Fossilze bug tracker https://github.com/ValveSoftware/Fossilize/issues/300.

I was able to mitigate the issue by disabling Shader Pre-Caching.

Steps for reproducing this issue:

  1. Play Warframe on Steam.
