Open christophe-lunarg opened this issue 2 months ago • 0 comments

Describe the bug Here is a case we encountered with @artem-lunarg: When running a Vulkan application and enabling(trying) the validation layer with VK_INSTANCE_LAYERS and a vk_loader_settings.json that only include the drivers section (generated by Vulkan Configurator), the validation layer is not enabled.

VK_INSTANCE_LAYERS should be ignored only is the layers section is written to vk_loader_settings.json

Environment (please complete the following information):

OS: Reproduced on Windows
Bitdepth: 64-bit
October 2025 SDK
Enabled layers: Validation layer
