Can you provide the output of vulkaninfo (without setting VK_ICD_FILENAMES) for both cases? > To circumvent the problem with the mesa-vulkan-drivers upgraded I had to set > VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json > in my Xession init scripts to force Nvidia Vulkan driver. It's rather doubtful that there's a bug here. Without setting VK_ICD_FILENAMES, there's no well-defined order in which Vulkan devices are enumerated. Most Vulkan applications just use the first enumerated device, so if the enumeration order changes, they'll end up using a different one. -- Earthling Michel Dänzer | https://redhat.com Libre software enthusiast | Mesa and Xwayland developer
