Gamescope not working Assertion `u8BitFormat != VK_FORMAT_UNDEFINED' failed
Whenever I try to use gamescope with any game (steam and no steam as well) I get the following error:
gamescope: ../gamescope/src/wayland_backend.cpp:1280: virtual void gamescope::CWaylandBackend::GetPreferredOutputFormat(VkFormat*, VkFormat*) const: Assertion u8BitFormat != VK_FORMAT_UNDEFINED' failed.`
Here's the full output:
ATTENTION: default value of option vk_khr_present_wait overridden by environment.

I tried using both gamescope and gamescope-git, same error using both. I'm using arch linux and my gpu is AMD Radeon RX 580 with RADV drivers (amdvlk is not installed).
I wasn't getting this error when I first installed gamescope like 1 and a half month ago, so maybe it broke with an update. Also here's journalctl's log:
