When testing Trainz from issue https://github.com/doitsujin/dxvk/issues/2429 i tried launching run_directx.bat through Proton experimental as a non Steam game with validation layers on

VK_INSTANCE_LAYERS=VK_LAYER_KHRONOS_validation DXVK_DEBUG=validation PROTON_LOG=1 %command%

Like with regular Wine it crashes at start with with dxvk 2.0 together with Vulkan validation but unlike regular Wine Proton experimental throws out the error below.

err:   VUID-VkSubmitInfo2-semaphore-03881: 
err:   Validation Error: [ VUID-VkSubmitInfo2-semaphore-03881 ] Object 0: handle = 0x27d60e0000000019, type = VK_OBJECT_TYPE_UNKNOWN; Object 1: handle = 0x7edf8b70, type = VK_OBJECT_TYPE_QUEUE; | MessageID = 0x966cd5a6 | vkQueueSubmit2(): pSubmits[0].pSignalSemaphoreInfos[0] signal value (0x1) in VkQueue 0x7edf8b70[] must be greater than current timeline semaphore VkNonDispatchableHandle 0x27d60e0000000019[] value (0x6e696168) The Vulkan spec states: If the same semaphore is used as the semaphore member of both an element of pSignalSemaphoreInfos and pWaitSemaphoreInfos, and that semaphore is a timeline semaphore, the value member of the pSignalSemaphoreInfos element must be greater than the value member of the pWaitSemaphoreInfos element (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-VkSubmitInfo2-semaphore-03881)
