AVDCreateGPUAccelerator: Error loading GPU renderer on MacPro Qt 5.6.x/5.9.2

  • 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/] Error creating context.
    is still there. But at least WebGL is working.
