After integrating VTK 5.10.1 (from 5.8), we noticed this problem where image data disappears and reappears when clicking the mouse within the view. The behavior is not consistent: you can click in one view, and the image data in another view disappears, for example.
This problem was seen on a machine having only integrated graphics -- Intel HD Graphic 2000. We did not see it on machines with dedicated graphics cards (e.g. NVIDIA Quadro 3000M).
We were able to work around the problem in the following 2 ways, which suggests a relationship to vtkRenderedAreaPicker and vtkRenderer Layer:
- Remove picking code which uses vtkRenderedAreaPicker
- Move overlay actors (rulers and orientation labels) from a dedicated renderer layer to the primary renderer layer (0).
