<Discrete GPU> Metal backend - AMD Radeon R9 M395
[Default Toggle Names]
always_resolve_into_zero_level_and_layer: https://crbug.com/dawn/56: When the resolve target is a texture view that is created on the non-zero level or layer of a texture, we first resolve into a temporarily 2D texture with only one mipmap level and one array layer, and copy the result of MSAA resolve into the true resolve target. This workaround is enabled by default on the Metal drivers that have bugs when setting non-zero resolveLevel or resolveSlice. It is also enabled by default on Qualcomm Vulkan drivers, which have similar bugs.
lazy_clear_resource_on_first_use: https://crbug.com/dawn/145: Clears resource to zero on first usage. This initializes the resource so that no dirty bits from recycled memory is present in the new resource.
metal_enable_vertex_pulling: https://crbug.com/dawn/480: Uses vertex pulling to protect out-of-bounds reads on Metal
disallow_unsafe_apis: http://crbug.com/1138528: Produces validation errors on API entry points or parameter combinations that aren't considered secure yet.
metal_use_combined_depth_stencil_format_for_stencil8: https://crbug.com/dawn/1389: Use a combined depth stencil format instead of stencil8. Works around an issue where the stencil8 format alone does not work correctly. This toggle also causes depth stencil attachments using a stencil8 format to also set the depth attachment in the Metal render pass. This works around another issue where Metal fails to set the stencil attachment correctly for a combined depth stencil format if the depth attachment is not also set.
metal_use_both_depth_and_stencil_attachments_for_combined_depth_stencil_formats: https://crbug.com/dawn/1389: In Metal, depth and stencil attachments are set separately. Setting just one without the other does not work correctly for combined depth stencil formats on some Metal drivers. This workarounds ensures that both are set. This situation arises during lazy clears, or for stencil8 formats if metal_use_combined_depth_stencil_format_for_stencil8 is also enabled.

use_temporary_buffer_in_texture_to_texture_copy: https://crbug.com/dawn/42: Split texture-to-texture copy into two copies: copy from source texture into a temporary buffer, and copy from the temporary buffer into the destination texture when copying between compressed textures that don't have block-aligned sizes. This workaround is enabled by default on all Vulkan drivers to solve an issue in the Vulkan SPEC about the texture-to-texture copies with compressed formats. See #1005 (https://github.com/KhronosGroup/Vulkan-Docs/issues/1005) for more details.
vulkan_use_d32s8: https://crbug.com/dawn/286: Vulkan mandates support of either D32_FLOAT_S8 or D24_UNORM_S8. When available the backend will use D32S8 (toggle to on) but setting the toggle to off will make it use the D24S8 format when possible.
vulkan_use_s8: https://crbug.com/dawn/666: Vulkan has a pure stencil8 format but it is not universally available. When this toggle is on, the backend will use S8 for the stencil8 format, otherwise it will fallback to D32S8 or D24S8.
