Yeah, that can happen — Steam Cloud is supposed to be cross-platform, but in practice the save path can be different depending on the OS. On Linux (Kubuntu) sometimes Proton/Wine puts the saves in a different directory than Windows does, so even if Steam says it synced, the game itself might not be reading from the same place.

What you can try:
– Check the game’s compatdata folder under ~/.steam/steam/steamapps/compatdata/ and look for where the demo is actually storing saves.
– Compare that with where Windows puts them, and if needed, manually copy the files.
– You can also try disabling Steam Cloud temporarily, copy the saves manually into the Proton prefix, and then re-enable it — that sometimes forces Steam to sync the correct folder.

So yeah, it’s not that Steam Cloud is totally failing, it’s just that Linux + Proton sometimes points the game to a different path than Windows.

Thank you for the reply. I'm a new Linux user actually, so I'm still learning about how the file system works. I see the directory you're talking about, but I'm not sure what I'm looking at. The directories within the compatdata directory are all titled a bunch of numbers, and are full of what I guess is Wine data. None of it looks specific to my game's save data though.

Is there any documentation for the game save data online that I could refer to? I haven't found anything from my searches. Also, would I have to copy the save data over manually each time, or would it fix the sync itself after I copy it?
