Synchronization validation error with dynamic rendering sample #1136

Closed lwjglgamedev closed 3 months ago

lwjglgamedev commented 3 months ago

When testing the dynamic rendering sample, with synchronization validation layers enabled, I get the following error:

SYNC-HAZARD-WRITE-AFTER-READ(ERROR / SPEC): msgNum: 929810911 - Validation Error: [ SYNC-HAZARD-WRITE-AFTER-READ ] Object 0: handle = 0x2f856cf8, type = VK_OBJECT_TYPE_QUEUE; | MessageID = 0x376bc9df | vkQueueSubmit():  Hazard WRITE_AFTER_READ for entry 0, VkCommandBuffer 0x2f8fcca0[], Submitted access info (submitted_usage: SYNC_IMAGE_LAYOUT_TRANSITION, command: vkCmdPipelineBarrier, seq_no: 1, reset_no: 3).

I'm testing it with Fedora 40, and have installed latest Vulkan SDK (1.3.290.0). This the configuration of the validation layers:
