Has any progress been made on this problem? I'm still encountering it. If it helps at all, I'm running on a Linux system with noVNC.

Hi,

I can't answer to that directly.

Can you provide a minimal compilable example that shows that behaviour ?

What you see is the "default" light. AFAIK you can get no pointer to the default light to change its position, color, intensity or the like. If you want to have control you will have to add your own light to the root entity which then replaces the "default" light by some internal magic.

So you do something like this:

m_pLight=new Qt3DRender::QPointLight();
Qt3DCore::QEntity *pLightEntity=new Qt3DCore::QEntity(m_pRootEntity);
pLightEntity->addComponent(m_pLight);
m_pLight->setIntensity(m_fLightPower);

hi did u fix it ,i also encout this problem when delete or add a 3DObject to QT3DWindow.. it seems have no convnient api to do this

@Keyos I meet the same problem,and when i launch my app,the memory usage become 50% even the dialog is not actived,maybe the next release will be better.
