[Dawn Native] VK_ERROR_DEVICE_LOST when drag resizing window

[Kurtis Fields]

OS:  Ubuntu 24.04
GPU:  RTX 2060
BACKEND: Vulkan

Has anyone else experienced this problem?
It happens with both SDL3 and GLFW.
Less so with GLFW.  I have to aggressively resize the window but I think this is because GLFW has a timer/throttle on the resize callback.

I fixed it by adding DeviceWaitIdle  in SwapChainVk.cpp:

MaybeError SwapChain::Initialize(SwapChainBase* previousSwapChain) {

Device* device = ToBackend(GetDevice());

PhysicalDevice* physicalDevice = ToBackend(GetDevice()->GetPhysicalDevice());

VkSwapchainKHR previousVkSwapChain = VK_NULL_HANDLE;

if (previousSwapChain != nullptr) {

// TODO(crbug.com/dawn/269): The first time a surface is used with a Device, check

// it is supported with vkGetPhysicalDeviceSurfaceSupportKHR.

// TODO(crbug.com/dawn/269): figure out what should happen when surfaces are used by

// multiple backends one after the other. It probably needs to block until the backend

// and GPU are completely finished with the previous swapchain.

DAWN_TRY(CheckVkSuccess(

device->fn.DeviceWaitIdle(device->GetVkDevice()),

"DeviceWaitIdle"));

Should I file a bug report?

This sounds a lot like https://crbug.com/403297812 (search page for VK_ERROR_DEVICE_LOST), but that should be mostly fixed. Still, might be related.

If you can provide a reproduction case (or if it happens in an existing sample), a bug report would be appreciated! https://crbug.com/dawn/new

Please include info about your GPU driver, x11 vs wayland, display refresh rate, and anything else that might be relevant.
