Hi,
Thanks for the fix! the null-returning paintEngine solved flickering problem
for me as well. I am using a simplified osgviewerQtWidget and the flickering

Thank you!

I'm glad the null-returning QPaintEngine function seems to work for you.
Unfortunately, I don't really have any other suggestions for testing
it to determine whether or not you should label the fix acceptable.
This is a question each project team must answer for

Greetings OpenSceneGraph/Qt users,
