after launching Gpu Caps Viewer with Vulkan demo, application crashes after trying to resize window rapidly.

Validation Layers (specifically: LunarG: Core Validation) have shown error with creation of a swapchain:

QuoteVUID-VkSwapchainCreateInfoKHR-imageExtent-01274(ERROR / SPEC): msgNum: 0 - vkCreateSwapchainKHR() called with imageExtent = (235,8), which is outside the bounds returned by vkGetPhysicalDeviceSurfaceCapabilitiesKHR(): currentExtent = (239,18), minImageExtent = (239,18), maxImageExtent = (239,18). The Vulkan spec states: imageExtent must be between minImageExtent and maxImageExtent, inclusive, where minImageExtent and maxImageExtent are members of the VkSurfaceCapabilitiesKHR structure returned by vkGetPhysicalDeviceSurfaceCapabilitiesKHR for the surface (

Issue is observed on:
1. Intel KBL platform with driver version 6229
2. nVidia Quadro K600 with driver version

To reproduce:
1. Launch demo:
    " GPU_Caps_Viewer.exe /run_gxl_demo=vk_shadertoy_geomechanical /benchmark_log_results /demo_msaa=0 /vk_gpu_index=0 "
2. Then just grab window corner and resize up/down rapidly.


GPU Caps Viewer 1.42.4 is based on an old GeeXLab SDK with an old Vulkan plugin. I will check this issue with the new SDK and update GPU Caps Viewer... Thanks for the feedback  ;)


I reproduced the issue with latest Vulkan validation layers (Vulkan SDK 1.1.121). This bug is added on my kill-list!


I fixed the issue. The fix will be available in the next GPU Caps Viewer and in GeeXLab 0.29.1+.
