Slasher's Keep Unplayable (Spawns character floating in the sky)
Instead of displaying the dungeon and a map of the dungeon, only the skybox and a bugged map are visible. The game is not playable on my machine with either direct3d 9 or its default graphics API. I tried all available versions of proton, as well as uninstalling and reinstalling several times but had no luck.
Works perfectly out of the box!

Ran fine on ChimeraOS!
Ran fine on both my Steam Deck and my purpose-built ChimeraOS Steam Machine for the living room with an Xbox Controller. I'm pretty terrible at it, but it works fine!
Runs great and works out of the box with Proton

Worked out of the box.
Perfect out of the box, no issues at all. Using default proton no tweaks or changes.
If it were not for the initial Steam Play notification when launching the game I don't think most users would know they were running the game in Linux.
Graphical glitches disappeared after downgrading to Proton 5.0-10
Whole screen was overlaid with a semitransparent glitchy texture
Worked out of the box, no issues.
This game runs perfectly out of the box! No tweaks needed.
Game works flawlessly with current Proton (5.13-2), only minor issues when using i3 window manager
Only a minor issue. On i3 switching workspaces itself works but the game immediately grabs the cursor again. Played in maximized windowed mode. When using Alt+Enter to switch from fullscreen to windowed mode when there's another window on the workspace in tiled mode ,and then switching back to fullscreen distorts the UI a bit and the menu can't be properly used anymore. When using i3 I recommend playing in maximized windowed mode (basically on its own workspace in non-floating mode)
