            Bug ID: 103538
           Summary: vkDestroySwapchain causes deadlock on Wayland
                    compositor with X11
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Vulkan/radeon
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: maister at archlinux.us
        QA Contact: mesa-dev at lists.freedesktop.org

When using the X11 backend in GLFW on RADV (and Anvil for that matter), when
tearing down the device, vkDestroySwapchain deadlocks while waiting for a
thread to complete execution. vkDeviceWaitIdle() has been called prior.
