Hi,

I have qt app with tab widget with two views in one compositeviewer
When I switch tab I'd like not to render invisible window.
I browse source and not found any method to disable rendering on certain view

Thank you!

Cheers,
Roman

Roman,

Have you tried view->getCamera()->setNodeMask(0x0)?

yes I tried to do this but I have active second context and have qt warnings
QOpenGLContext::swapBuffers() called with non-exposed window, behavior is undefined
so it doesn't help
even more if I have Vsync On to 60fps I have only 30 fps in null scenegraph in both windows and if I add to compositeviewer only one view I got 60 fps.
