Hello,
First of all apologies for possible lack of knowledge, I’ve been daily driving linux for a year and just recently switched to CachyOS.
Issue is, that I am steam remote playing on daily basis on local network. I switched recently to cachyos on both steam deck as client on main pc as host, super cool I thought to myself.
I have a problem however to which i found no answer. My client is not connecting to host (despite opening the appropriate ports) and if he does - he causes the host to not be able to fully close game process. Steam is displaying that game as running despite nothing being on screen and I can RAM usage is building up.
Am really at my wits end and I don’t know how to solve it at this point.
Thank You for any help in advance
i think this is issue on steam,

#### Please describe your issue in as much detail as possible:
When I attempt to stream a game from the computer described above as host, to another computer on the LAN also logged in on my account (not Steam Link or Remote Play Together, neither of those work either but that's been the case for a while and is not the issue I'm currently describing), the host's Steam instance crashes and immediately restarts. This occurs shortly after the game to be streamed starts up on the host side, while in the stream-loading splash screen (the one tiled with the game's art). When I do this after opening Steam through the terminal so as to watch stdout/stderr, nothing is logged on the client side. On the host side, at the time of the crash, the following is logged without any preceding error:

This occurs for every game I try to stream, and all of these games work properly on the host machine when not attempting to stream.
This began occurring on 2026-05-29. Previously, I streamed various games between these two machines every few days without error, most recently on the 28th. The host machine had not had any software updates run between the last successful and first unsuccessful stream. The client machine is capable of streaming Steam games from a different host machine on the same local network.
The above occurs consistently over many attempts, with a single exception, in which the crash occurred before the game started up, accompanied by an error popup reading "Unable to initialize SteamAPI. Please make sure Steam is running and you are logged in to an account entitled to the game."
#### Steps for reproducing this issue:
1. Start Steam on both host and client machines.
2. On client machine, click the "Stream" button that appears in place of the usual "Play" button once Steam is started on the host and recognized by the client.
3. Wait for the game to start-and-crash.
not exactly, the game starts, but the steam fails. i’m starti g to thing it’s an error due to shared btrfs partio. between garuda and cachy. i’ll test further
i mean, it’s happens on me myself lmao, i’ve tested it before posting in here, and in the end i gave up
fuck, everything was working on garuda untill i installed cachyos on different partition
I found out when it’s happening - it’s happening when host needs to pre-compile shaders
I think I’ll have to reinstall them on different drives
