VTK not clearing previous frame and filling background - qt

Question

I've installed VTK 8.2.0 with CMake for use with QT but when trying to run some VTK examples I have some issues shown below:
Note: The colour banding issues in the image is from the gif compression and is not part of the issue
#include <vtkSmartPointer.h>
#include <vtkActor.h>
#include <vtkCubeSource.h>
#include <vtkPolyData.h>
#include <vtkPolyDataMapper.h>
#include <vtkRenderWindow.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkRenderer.h>
int main(int, char *[])
{
// Create a cube.
vtkSmartPointer<vtkCubeSource> cubeSource =
vtkSmartPointer<vtkCubeSource>::New();
// Create a mapper and actor.
vtkSmartPointer<vtkPolyDataMapper> mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputConnection(cubeSource->GetOutputPort());
vtkSmartPointer<vtkActor> actor =
vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);
// Create a renderer, render window, and interactor
vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkRenderer>::New();
vtkSmartPointer<vtkRenderWindow> renderWindow =
vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->AddRenderer(renderer);
vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetRenderWindow(renderWindow);
// Add the actors to the scene
renderer->AddActor(actor);
renderer->SetBackground(.3, .2, .1);
// Render and interact
renderWindow->Render();
renderWindowInteractor->Start();
return EXIT_SUCCESS;
}

For all of the examples, it appears that the previous frame is not being cleared and the background is not being shown over it.
I don't appear to get any error messages when compiling or running the program. Might it be a driver issue?
Any help would be much appreciated!
