ANGLE Features
• disable_program_caching_for_transform_feedback (Frontend workarounds): Disabled
On some GPUs, program binaries don’t contain transform feedback varyings
• lose_context_on_out_of_memory (Frontend workarounds): Enabled: true
Some users rely on a lost context notification if a GL_OUT_OF_MEMORY error occurs
• scalarize_vec_and_mat_constructor_args (Frontend workarounds) 398694: Enabled: true
Always rewrite vec/mat constructors to be consistent
• sync_framebuffer_bindings_on_tex_image (Frontend workarounds): Disabled
On some drivers TexImage sometimes seems to interact with the Framebuffer
• add_dummy_texture_no_render_target (D3D workarounds) anglebug:2152: Disabled: isIntel && capsVersion < IntelDriverVersion(4815)
On some drivers when rendering with no render target, two bugs lead to incorrect behavior
• allow_clear_for_robust_resource_init (D3D workarounds) 941620: Enabled: true
Some drivers corrupt texture data when clearing for robust resource initialization.
• call_clear_twice (D3D workarounds) 655534: Disabled: isIntel && isSkylake && capsVersion < IntelDriverVersion(4771)
Using clear() may not take effect
• depth_stencil_blit_extra_copy (D3D workarounds) anglebug:1452: Disabled
Bug in some drivers triggers a TDR when using CopySubresourceRegion from a staging texture to a depth/stencil
• disable_b5g6r5_support (D3D workarounds): Disabled: (isIntel && capsVersion < IntelDriverVersion(4539)) || isAMD
Textures with the format DXGI_FORMAT_B5G6R5_UNORM have incorrect data
• dont_translate_uniform_block_to_structured_buffer (D3D workarounds): Enabled: true
Fails to allocate ShaderResourceView for StructuredBuffer on some drivers
• emulate_isnan_float (D3D workarounds) 650547: Disabled: isIntel && isSkylake && capsVersion < IntelDriverVersion(4542)
Using isnan() on highp float will get wrong answer
• emulate_tiny_stencil_textures (D3D workarounds): Disabled: isAMD && !(deviceCaps.featureLevel < D3D_FEATURE_LEVEL_10_1)
1×1 and 2×2 mips of depth/stencil textures aren’t sampled correctly
• expand_integer_pow_expressions (D3D workarounds): Enabled: true
The HLSL optimizer has a bug with optimizing ‘pow’ in certain integer-valued expressions
• flush_after_ending_transform_feedback (D3D workarounds): Disabled: isNvidia
Some drivers sometimes write out-of-order results to StreamOut buffers when transform feedback is used to repeatedly write to the same buffer positions
• force_atomic_value_resolution (D3D workarounds) anglebug:3246: Disabled: isNvidia
On some drivers the return value from RWByteAddressBuffer.InterlockedAdd does not resolve when used in the .yzw components of a RWByteAddressBuffer.Store operation
• get_dimensions_ignores_base_level (D3D workarounds): Disabled: isNvidia
Some drivers do not take into account the base level of the texture in the results of the HLSL GetDimensions builtin
• mrt_perf_workaround (D3D workarounds): Enabled: true
Some drivers have a bug where they ignore null render targets
• pre_add_texel_fetch_offsets (D3D workarounds): Enabled: isIntel
HLSL’s function texture.Load returns 0 when the parameter Location is negative, even if the sum of Offset and Location is in range
• rewrite_unary_minus_operator (D3D workarounds): Disabled: isIntel && (isBroadwell || isHaswell) && capsVersion < IntelDriverVersion(4624)
Evaluating unary minus operator on integer may get wrong answer in vertex shaders
• select_view_in_geometry_shader (D3D workarounds): Enabled: !deviceCaps.supportsVpRtIndexWriteFromVertexShader
The viewport or render target slice will be selected in the geometry shader stage for the ANGLE_multiview extension
• set_data_faster_than_image_upload (D3D workarounds): Enabled: !(isIvyBridge || isBroadwell || isHaswell)
Set data faster than image upload
• skip_vs_constant_register_zero (D3D workarounds): Disabled: isNvidia
In specific cases the driver doesn’t handle constant register zero correctly
• use_instanced_point_sprite_emulation (D3D workarounds): Disabled: isFeatureLevel9_3
Some D3D11 renderers do not support geometry shaders for pointsprite emulation
• use_system_memory_for_constant_buffers (D3D workarounds) 593024: Enabled: isIntel
Copying from staging storage to constant buffer storage does not work
• zero_max_lod (D3D workarounds): Disabled: isFeatureLevel9_3
Missing an option to disable mipmaps on a mipmapped texture
