Looking at some info online and after some research it does seem that RenderDoc does not reliably support VK_MEMORY_PROPERTY_LAZILY_ALLOCATED_BIT, especially on tiled GPUs (Adreno), and it can alter memoryTypeBits during injection.

I think that you should keep your current workaround 

if (isRenderDoc)

disable VK_MEMORY_PROPERTY_LAZILY_ALLOCATED_BIT;

And detect RenderDoc via:

    • VK_LAYER_RENDERDOC_Capture
    • or env/debug flags

You will have to disable it for capture/debug builds though
