    Hi,
    I experience same error as mentioned here:: QWebEngineView has error webgl pages on mac pro

    After trying bunch of Chromium flags I could not get WebGL working in QWebEngineView at all.

    Does anyone know the workaround?

      I leave this here for anyone having same issue:
      Add QTWEBENGINE_CHROMIUM_FLAGS="--supports-dual-gpus=true" or pass it over command line arguments.
      By default, Qt runs WebEngine with --supports-dual-gpus=false while Chrome doesn't.
      Allowing dual GPUs makes the magic. However,
      [26155:70403:0417/122744:ERROR:gl_context_cgl.cc(129)] Error creating context.
      is still there. But at least WebGL is working.
