Hi, I’m a VTK beginner, and I have a strange problem when I ran the VTK example, which was that setting the renderer’s background color would sometimes fail and the background would turn black, and dragging the actor instance would create a drag.Both python and qt occur this problem.
The following screenshot shows this problem when SetBackground is set to (1.0,1.0,0.5).
But when SetBackground is set to (1.0,1.0,0.5) this problem disappeared.
This problem occurs in python too.
I hope you can help me, thank you very much.And please forgive my broken English
