strange problems when running the examples in different languages

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.

It’s like every example in the GeometricObjects module have this problem.

I’m sure to have seen this issue reported already, but could not find where it was.
Must have been on discourse or gitlab.

This is probably a driver issue.

Here it is.
