Hello @grimshins, please copy your system information from Steam (Steam -> Help -> System Information) and put it in a gist, then include a link to the gist in this issue report. Also, if you completely close Steam, then run steam from a terminal, are there any hints in the terminal spew to go along with trying to run a game?
Nevermind, I see the issue here.
So, the issue is a regression somewhere in mesa/dozen which causes it to interfere with 64 bit mesa/radv. In the short term, you can temporarily disable this driver with something like sudo mv /usr/share/vulkan/icd.d/dzn_icd.x86_64.json /usr/share/vulkan/icd.d/dzn_icd.x86_64.json.disabled or run steam with VK_ICD_FILENAMES="/usr/share/vulkan/icd.d/radeon_icd.x86_64.json:/usr/share/vulkan/icd.d/radeon_icd.i686.json steam from a terminal to avoid the driver as well.
This is clearly a mesa issue and needs to be pondered by a mesa dev. Please report it to mesa's gitlab issue tracker. I'll get a revised mesa build sent off to the build farm shortly.
Closing as not a Steam client issue.
Nothing extracted yet.
