They aren’t going to make their own desktop. That’s just not gonna happen. They’ll use KDE as before, and that’s just the facts. I’m not saying they will make anything other than a VR-style compositor to select standard 2D virtual desktops. That’s simple and effective, and doesn’t require building a whole new thing.











Just don’t run this version of Proton with this game.
The reason they make all versions of Proton available at all times is because the rolling Proton version may break game configs for various reasons, in this case it looks like a Vulkan rendering queue issue where the call is blocking: https://docs.vulkan.org/refpages/latest/refpages/source/vkQueuePresentKHR.html
You can check ProtonDB to see if anyone has a workaround for newer versions of Proton, but it’s mostly unnecessary unless there’s some specific features a specific point release you care about. Just pin the game to a working version and go.
