Problems Detected
GPU process was unable to boot: Features are disabled upon full but not preliminary GPU info.
Disabled Features: all
Accelerated video decode interferes with GPU sandbox on older Intel drivers: 180695, 298968, 436968
Disabled Features: accelerated_video_decode
Some drivers are unable to reset the D3D device in the GPU process sandbox
Applied Workarounds: exit_on_context_lost
TexSubImage is faster for full uploads on ANGLE
Applied Workarounds: texsubimage_faster_than_teximage
Clear uniforms before first program use on all platforms: 124764, 349137
Applied Workarounds: clear_uniforms_before_first_program_use
Always rewrite vec/mat constructors to be consistent: 398694
Applied Workarounds: scalarize_vec_and_mat_constructor_args
Old Intel drivers cannot reliably support D3D11: 363721
Applied Workarounds: disable_d3d11
ANGLE crash on glReadPixels from incomplete cube map texture: 518889
Applied Workarounds: force_cube_complete
On Intel GPUs MSAA performance is not acceptable for GPU rasterization: 527565
Applied Workarounds: disable_msaa_on_non_webgl_contexts
Framebuffer discarding can hurt performance on non-tilers: 570897
Applied Workarounds: disable_discard_framebuffer
Accelerated rasterization has been disabled, either via about:flags or command line.
Disabled Features: rasterization
Raster is using a single thread.
Disabled Features: multiple_raster_threads
Native GpuMemoryBuffers have been disabled, either via about:flags or command line.
Disabled Features: native_gpu_memory_buffers
