Rendering outside a View Glitches

[vooidptr]

Hello,

I try to embed a View in application with Quick Controls 2, but they are some glitches :

• The ApplicationWindow rendering fails : it has black background (and I cannot change it)
• Widgets are correctly rendering when they are inside a View, but if I put them outside the rendering is not correct. (See Video.zip)

You can find the minimal example I use in video here

I tried to change the QSG_RENDER_LOOP both to threaded and basic but same results happened.

May be the rendering process has some difficulties to sync Qt rendering loop with osg rendering loop ? I use Qt 5.9 on Windows 10.

Thanks :)
