QVTKOpenGLSimpleWidget black screen
I have run into issues with QVTKOpenGLSimpleWidget. Applications built with a previous VTK version from a couple of months back work fine but when using the newest version the window either turns black once the mouse is clicked into it or is black from the beginning.
When running the tests associated with QVTKOpenGLSimpleWidget using ctest the test window pops up and displays the correct test result but I can't figure out how to run a single test and interact with it - apologies but I am a beginner when it comes to testing.
I have created a simple example, see the 3 files attached. This example reproduces the black screen without displaying an actor on application startup but works fine with the older compiled libraries.
