Description
I have a QML sample that redraws the QML UI every frame.
When running it with the Vulkan backend with validation layers enabled, the console is spammed with the following validation error:
vkDebug: Validation Error: [ VUID-vkAcquireNextImageKHR-semaphore-01779 ] Object 0: handle = 0xd5b26f0000000010, type = VK_OBJECT_TYPE_SEMAPHORE; | MessageID = 0x5717e75b | vkAcquireNextImageKHR(): Semaphore must not have any pending operations. The Vulkan spec states: If semaphore is not VK_NULL_HANDLE, it must not have any uncompleted signal or wait operations pending (https://vulkan.lunarg.com/doc/view/1.4.304.0/windows/1.4-extensions/vkspec.html#VUID-vkAcquireNextImageKHR-semaphore-01779)
I have included the mentioned sample in this issue.
