Please describe your issue in as much detail as possible:

After playing No Man's Sky for a while (often a few hours at a stretch), I quit and do some other things and then decide to run a Flatpak app (Chrome in this case), which I've added as a non-Steam game. Chrome does not start.

After investigation, I find that the log file /run/user/1000/gamescope-session.log is 1.5GB in size and has filled the entire 1.5GB tmpfs. In my case, it contains 15,379,037 instances of this line:

src/clientdll/controller.cpp (12866) : Assertion Failed: AppID 275850 exceeding analog action limits

After deletion of this log file and restarting Steam, or after rebooting, I'm able to launch Chrome and other Flatpak apps again.

Steps for reproducing this issue:

1. Boot Steam Deck in game mode
2. Play No Man's Sky (275850) for a couple hours docked, quit and return to game mode
3. Try to launch Chrome

To be clear, the reason Chrome is failing to run is because Flatpak is unable to create temporary files in /run/user/1000/, which is how I discovered the issue.

Oops, didn't mean to close

Hate when that happens

This should be fixed in SteamOS 3.6 (currently in beta).

3.6 stable is now out, and I think that this can be closed.

Confirmed fixed. There is no longer any log file consuming all available memory! :P
