Same thing happened for me on outlast.
I'm now getting this for Don't Starve Together on Arch Linux, having performed the same reproduction steps. It looks like once Proton is enabled for a game once, it will always will download and install the Windows version of that game even if "Force the use of a specific Steam Play compatibility tool" is unticked when Steam is restarted.
Workaround is to enable Proton for the game and then disable it again, then allow the game to update. However, this only lasts until Steam is restarted.
EDIT: Additional client information:
I'm experiencing this same issue for Garry's Mod.
For what it's worth, I've found that this stops if you manually delete the compadata directory for the affected game, which serves as a workaround. I guess there's some behaviour on startup that checks if a game has compatdata and tries to pull the latest Windows version if that succeeds.
I think that this happened to me with XCOM 2:
I had this happen this evening with Midnight Protocol. I tested a Proton version while diagnosing a performance issue, and after switching the "Force the use of..." off, it reverted back to the native binary as expected. However, the next time Steam was launched it "updated" the game, deploying the Windows assets instead.
This is frustrated by or related to #9957, which I can also reproduce (you can't switch off SteamPlay in the global steam settings anymore, the toggle does nothing).
Hello @draeath, per https://github.com/ValveSoftware/steam-for-linux/issues/9875#issuecomment-1853037408, please opt into Steam's client beta and retest.
Meee too, with Dirt4, and the downloads for the windows and linux versions are quite bulky. I'll go try the tip of removing the compdata ditectory.
This still occurs. Team Fortress 2 continues to download the Windows version even when Proton is disabled. It can be fixed by enabling and disabling Steam Linux Runtime 1.0 but this is not ideal.
Can confirm this still occurs.
Steam Play off
No force proton
And Steam keeps downloading for me the Windows version of Valheim instead of the native one every time I log-in on Steam
The workaround I found is uninstalling Steam through bauh and reinstalling Steam again
All I want is to switch between Proton/Native to see the difference between versions but once I enable the Proton it lingers until I reinstall or tick the force proton and untick again to get back the native(even though it was already unticked)
I have the exact same issue I'm just going to reinstall steam
I had the same issue with Stardew Valley.
Temporary fix is to go to the game properties -> Compatibility, then click "Force the use of a specific Steam Play compatibility tool" twitce, so it toggles on and then back off again. Then your game will download the native version. However the next time you launch Steam it will revert back to the compatibility version.
I tried @MCazaly's fix of deleting the compatdata folder for the game, but that did not fix the issue for me.
What fixed it permanently for me:
ok I solved it definitively but not with the method said above
Manualy copy you savefiles and put some game (not those you can't run in native) in other disks.
rm -rf ~/.local/share/Steam && rm -rf ~/.steam*
Then
steam
It should work because distribution keep the installer
problem 100% solved.
Your system information
Please describe your issue in as much detail as possible:
I was recently playing through Feral Interactive's Linux port of Shadow of the Tomb Raider. Unfortunately, I reached a particular spot where the game would consistently crash. To get around this, I uninstalled the game, enabled Steam Play-Proton, reinstalled the game and played beyond the troubled point. After that, I uninstalled the game, disabled Steam Play-Proton and reinstalled the game. However, I would get an error message on launch stating that the .sh launcher was missing. After checking the game folder, in steamapps/common, the Windows version of the game was downloaded instead of the Linux native version.
Steps for reproducing this issue:
Curious if this was specific to this title or not, I attempted to experiment with a few other games. Following the steps above, here are some results:
Amnesia: The Dark Descent
Steam Play off: Linux version
Steam Play on: Windows version
Steam Play off: Linux version
Alien: Isolation
Steam Play off: Linux version
Steam Play on: Windows version
SteamPlay off: Linux version
Dead Cells
Steam Play off: Linux version
Steam Play on: Windows version
Steam Play off: Windows version
Shadow of the Tomb Raider
Steam Play off: Linux version
Steam Play on: Windows version
Steam Play off: Windows version
I haven't tested the remaining Linux native supported titles in my library but, for some reason, some titles will only have the Windows version download if installed through Steam Play once. These results are reproducible with both the stable and beta versions of the Steam client. Please let me know if there is any further information I can help with. Cheers.
