SyncCommandBufferBuilderError(Conflict) On Successive Calls to AutoCommandBuffeBuilder::blit_image

[Neightro]

• Versions of Vulkano: 0.19.0 and 0.18.0
• OS: Linux (Kernel version: 5.6.15-1-MANJARO)
• GPU (the selected PhysicalDevice): AMD Radeon RX580
• GPU Driver: VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] (rev e7) (prog-if 00 [VGA controller])

Repository demonstrating the issue: https://github.com/Neightro/vulkan-tutorial-test
Branch master uses Vulkano 0.11.1 and works as expected. Branch 'version_0-19-0' uses the latest version and panics on a BlitImageError.

Issue

When adding image blitting commands to a command buffer, successive calls to AutoCommandBufferBuilder::blit_image return a SyncCommandBufferBuilderError(Conflict)). The tutorial I was following warns that this code "results in Validation Layer warnings and may not behave the same on all machines." In the time since the tutorial has been released, has a more reliable way of performing this type of blitting been introduced?

Does this issue still occur with the latest Vulkano?
