Vulkan: Avoid breaking render pass for vertex buffer conversion Adreno driver does not support VK_FORMAT_FEATURE_VERTEX_BUFFER_BIT for VK_FORMAT_R8G8B8A8_USCALED. This cases we hit fallback code path using GPU to do conversion. The conversion buffer gets reused since all access are from GPU, but that causes render pass break since there is a WAR hazard on the conversion buffer. This CL adds the isRenderPassStartedAndUsesBuffer check and allocate a new conversion buffer if reuse current buffer may break the render pass.
