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

[Andrii Anpilogov]

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.
