Problems Detected
Accelerated 2d canvas is unstable in Linux at the moment
Disabled Features: accelerated_2d_canvas
Accelerated video decode is unavailable on Linux: 137247
Disabled Features: accelerated_video_decode
EXT_occlusion_query appears to be buggy with Intel GPUs on Linux
Clear uniforms before first program use on all platforms: 124764, 349137
Applied Workarounds: clear_uniforms_before_first_program_use
Mesa drivers in Linux handle varyings without static use incorrectly: 333885
Applied Workarounds: count_all_in_varyings_packing
Disable partial swaps on linux drivers: 339493
Applied Workarounds: disable_post_sub_buffers_for_onscreen_surfaces
Always rewrite vec/mat constructors to be consistent: 398694
Applied Workarounds: scalarize_vec_and_mat_constructor_args
MakeCurrent is slow on Linux
Applied Workarounds: use_virtualized_gl_contexts
Accelerated rasterization has been disabled, either via about:flags or command line.
Disabled Features: rasterization
