GPU Caps Viewer 1.43.0.0 Vulkan demo becomes black during resize (triangle v2)

[Pawel]

Hi,

after launching Gpu Caps Viewer with Vulkan RGB triangle v2 demo, application window becomes black during resize.

This occurs for Gpu Caps viewer version 1.42.6.0 and 1.43.0.0

Validation Layers (specifically: LunarG: Core Validation) have shown e.g.:

UNASSIGNED-CoreValidation-DrawState-InvalidCommandBuffer-VkImageView(ERROR / SPEC): msgNum: 0 - You are adding vkQueueSubmit() to VkCommandBuffer 0x75ebed0[] that is invalid because bound VkImageView 0x76f2a40[] was destroyed.

  VUID-VkPresentInfoKHR-pImageIndices-01296(ERROR / SPEC): msgNum: 0 - Images passed to present must be in layout VK_IMAGE_LAYOUT_PRESENT_SRC_KHR or VK_IMAGE_LAYOUT_SHARED_PRESENT_KHR but is in VK_IMAGE_LAYOUT_COLOR_ATTACHMENT_OPTIMAL. The Vulkan spec states: Each element of pImageIndices must be the index of a presentable image acquired from the swapchain specified by the corresponding element of the pSwapchains array, and the presented image subresource must be in the VK_IMAGE_LAYOUT_PRESENT_SRC_KHR layout at the time the operation is executed on a VkDevice (https://www.khronos.org/registry/vulkan/specs/1.1-extensions/html/vkspec.html#VUID-VkPresentInfoKHR-pImageIndices-01296)

Issue was observed on:
1. Intel ICL platform (driver version: 26.20.100.7372)
2. nVidia Quadro K600 (driver version 26.21.14.3639).

To reproduce:
1. Run GPU Caps Viewer 1.42.6.0 or 1.43.0.0,
2. Open "Vulkan - RGB Triangle v2" demo from the "3D Demos" tab,
3. Drag window corner to resize it (do it for a for a few seconds).

Thanks for the feedback. I will check that issue as soon as possible.
What is the version of the Vulkan SDK ?

[Pawel]

Hi,

Version of the vulkan SDK is 1.1.121.2

[JeGX]

Indeed I reproduced the bug with a GeForce GPU and an Intel HD 630 GPU. I was sure I tested my Vulkan code last time without error with Vulkan SDK 1.1.126 and now, the swapchain resize code is full of warning and errors...

[JeGX]

I fixed the window resize bug in Vulkan. The fix will be available in the next GeeXLab 0.29.6+ and in GPU Caps Viewer 1.43.1+.
