ParaView 5.12.0-RC2: Enable Ray Tracing with "OSPRay pathtracer" performance and behavior is different from ParaView 5.11.2
Steps to reproduce:
- Start ParaView 5.12.0-RC2
- Sources -> Alphabetical -> Sphere
- In the properties panel, enable Advanced properties. Check the "Enable Ray Tracing" View property. Change the "Back End" to "OSPRay pathtracer".
- Click and drag in the render window. It takes several seconds for interaction to begin and then the frame rate is rather low.
- If you move the mouse over the render window, an additional pass appears to be made because the image changes from one with very obvious noise to one that is smooth. This does not match the behavior of ParaView 5.11.2.
