From f239bb8020df4176ca539bafff327ab5c8da2c2e Mon Sep 17 00:00:00 2001 From: Georg Lehmann Date: Thu, 6 Feb 2020 22:29:42 +0100 Subject: Vulkan Overlay: Don't try to change the image layout to present twice The render pass already does the transition. The pipeline barrier is still needed to transfer the queue family ownership.
