[Qtwebengine] QtWebEngine + WebGL + ANGLE + Intel + Windows?

[Matt]

Hello and thank you very much for your response. We suspected as much (re: ANGLE + WebGL) from the code but it's good to get an official confirmation. 
This is unfortunate for our project as we depend on WebGL web content, and while it does partially work with the mentioned flags, objects still show up black in some scenarios for some reason. The fact that Chrome browser exhibits the same behavior with desktop OpenGL does not bode well. We did see the bug report you mentioned and we did try the --disable_chromium_framebuffer_multisample flag, but unfortunately it doesn't help.
Is there a way to perhaps debug our specific issue to at least see which WebGL calls are failing? Perhaps some additional flags might help? Any advice is greatly appreciated. Thanks once again!
