Vulkan game does not work inside of gamescope

I'm trying to play Transport Fever 2 (native, without proton) inside of gamescope with vulkan. The OpenGL version works with gamescope, and both the OpenGL and Vulkan versions work without gamescope.

However, when launching Transport Fever 2 with vulkan enabled with these command line options gamescope -f -W 1920 -H 1080 --mangoapp -- %command% set in steam, the game fails to launch and displays the attached pop up error.
Steam/gamescope give the following output in the terminal:
[Gamescope WSI] Application info:
  pApplicationName: Transport Fever 2

Game Recording - game stopped [gameid=1066780]
Removing process 687862 for gameID 1066780

Any ideas on how to fix this?
