VkRenderingAreaInfoKHR manual isn't clear

[konstantinegorov]

From the VkRenderingAreaInfoKHR manual page:

either the extent.width member in renderArea is a multiple of the horizontal granularity or offset.x+extent.width is equal to the width of the framebuffer in the VkRenderPassBeginInfo

What does framebuffer width mean in case of dynamic rendering?

[gfxstrand]

After a bit of internal discussion, the framebuffer size is a little misleading with or without dynamic rendering. The real edge condition is if offset.x + extent.width is equal to the width of all of the bound attachment image views. It's possible to make a framebuffer with a size smaller than one or more of the attachments and, in that case, the render area lining up with the edge of the framebuffer is insufficient, even with render passes.
