below is part of my code

while (!glfwWindowShouldClose(window))
    {
        glfwPollEvents();
        // Get the next target texture view
        WGPUSurfaceTexture surfaceTexture;
        wgpuSurfaceGetCurrentTexture(surface, &surfaceTexture);

        if (surfaceTexture.status != WGPUSurfaceGetCurrentTextureStatus_Success)
        {
            continue; // Return NULL for failure case
        }
                // Create a view for this surface texture
        WGPUTextureViewDescriptor viewDescriptor;
        memset(&viewDescriptor, 0, sizeof(WGPUTextureViewDescriptor)); // Zero initialize the struct
        viewDescriptor.nextInChain = NULL;
        viewDescriptor.label = "Surface texture view";
        viewDescriptor.format = wgpuTextureGetFormat(surfaceTexture.texture);
        viewDescriptor.dimension = WGPUTextureViewDimension_2D;
        viewDescriptor.baseMipLevel = 0;
        viewDescriptor.mipLevelCount = 1;
        viewDescriptor.baseArrayLayer = 0;
        viewDescriptor.arrayLayerCount = 1;
        viewDescriptor.aspect = WGPUTextureAspect_All;

        // Create the texture view
        WGPUTextureView targetView = wgpuTextureCreateView(surfaceTexture.texture, &viewDescriptor);

        if (targetView == NULL)
        {
            continue;
        }
        ...
        ....

        // At the end of the frame, release the target texture view
        wgpuSurfacePresent(surface);
        wgpuTextureViewRelease(targetView);

        wgpuDevicePoll(device, false, NULL);

    }

Does it fix the issue to also release the surface texture with wgpuTextureRelease(surfaceTexture.texture); at the end of the loop?

[relaxslow]

yes ,wgpuTextureRelease(surfaceTexture.texture); solve the issue

[eliemichel]

That's curious because on my end I get a crash when releasing the surface texture, and the official spec suggests that wgpuSurfacePresent should take care of releasing whatever wgpuSurfaceGetCurrentTexture created.
