Describe the bug

When launching games via Steam/Heroic Launcher/Bottles Flatpak, they fail to start. However, in the native clients for Steam/Heroic, everything works fine. This issue occurs only with games running on Vulkan/DXVK, while games using OpenGL run without problems in Flatpak. Interestingly, if you run 'vulkaninfo', the games will start correctly until the next reboot.

To Reproduce

1. Launch Steam/Heroic Flatpak
2. Launch any game using Vulkan/DXVK
3. Get an error
