    Description

      We use layers with qml subpresentation running in a diffusemap.

      On our plattform ubuntu 16 we get black screen/ no rendering effects with the dragonrenderer in our application using the Qt3DStudio runtime 2.2.

      On the console we see warnings on startup like this:

      Qt3DRender::Dragon::GLTexture Qt3DRender::Dragon::createGlTexture(const Qt3DRender::Dragon::Immutable<Qt3DRender::Dragon::LoadedTexture>&, QOpenGLContext*) WARNING: Automatic format: 

      Later we get warnings like:

      QSize Qt3DRender::Dragon::ActivatedSurface::bindFrameBufferAttachmentHelper(uint, const Qt3DRender::Dragon::AttachmentPack&, Qt3DRender::Dragon::MutableContainer<Qt3DRender::Dragon::GLTexture>&) WARNING: Not implemented

       

      Turning off /or not enabling the dragonrenderer shows correct rendering.

      I suppplied a simple project using layer/diffusemap with qml streaming which shows the bug using it in a runtime2.2 based application. We turn on dragonrenderer with environment variable Q3DS_DRAGON=1.
