VK_EXT_Custom_Resolve question/problem

Vulkan Beta Driver: 582.35

When using VK_EXT_Custom_Resolve with dynamic rendering. I am seeing rendering output problems when using VK_ATTACHMENT_STORE_OP_DONT_CARE on the MSAA colour attachment. If I use VK_ATTACHMENT_STORE_OP_STORE then the problems go away.

My reading of the specification is the resolve attachment automatically gets VK_ATTACHMENT_STORE_OP_STORE and the MSAA colour attachment does not have to use VK_ATTACHMENT_STORE_OP_STORE.

The same program gives the expected results on a different driver.

There are no known validation errors.
