Thank you for letting me know! If you have the Vulkan SDK installed, could you give it a try with the validation layers enabled, i.e. `set VK_INSTANCE_LAYERS=VK_LAYER_LUNARG_standard_validation` followed by `rgo19` from the command-line? If we're hitting some device-specific limits this should give us a hint. What you could also try is toggling between the fullscreen and windowed mode with Alt+Enter and seeing if that makes any difference.
