</span>Finally a reproduction, I was beginning to despair :) Thanks a lot David.<br>
<br>
And just to make sure, Aron, did you run the test case as "TestCase<br>
1", with a parameter? That's the crucial thing, as otherwise it'll<br>
just use a regular vtkRenderWindow/<wbr>vtkRenderWindowInteractor (not<br>
QVTKOpenGLWidget), and not exhibit the problem.<br>
