Driver Bug Workarounds
======================
* enable_webgl_timer_query_extensions
* exit_on_context_lost
* rely_on_implicit_sync_for_swap_buffers
* disabled_extension_GL_KHR_blend_equation_advanced
* disabled_extension_GL_KHR_blend_equation_advanced_coherent
Problems Detected
=================
* WebGPU has been disabled via blocklist or the command line.
Disabled Features: webgpu
* Accelerated video encode has been disabled, either via blocklist, about:flags or the command line.
Disabled Features: video_encode
* Disable webgpu on vk via gl interop:
(http://crbug.com/442791440), (http://crbug.com/475935650)
Disabled Features: webgpu_on_vk_via_gl_interop
* Disable KHR_blend_equation_advanced until cc shaders are updated:
(http://crbug.com/661715)
Applied Workarounds: disable(GL_KHR_blend_equation_advanced),
disable(GL_KHR_blend_equation_advanced_coherent)
* Expose WebGL's disjoint_timer_query extensions on platforms with site isolation:
(http://crbug.com/808744), (http://crbug.com/870491)
Applied Workarounds: enable_webgl_timer_query_extensions
* Some drivers can't recover after OUT_OF_MEM and context lost:
(http://crbug.com/893177)
Applied Workarounds: exit_on_context_lost
* Avoid waiting on a egl fence before swapping buffers and rely on implicit sync on Broadcom GPUs:
(http://crbug.com/938286)
Applied Workarounds: rely_on_implicit_sync_for_swap_buffers
