Hello group, I could need some help figuring out the correct way to use a vtkShaderProgram2 from within a mitk::VtkMapper.
Currently, my mapper overrides MitkRenderOpaqueGeometry. When the method is called for the first time given a specific renderer, it builds a new vtkShaderProgram2 and adds it to its local storage. This way, rendering works as planned. It leads to no further problems if the mapper is destroyed manually. However, the program crashes if the workbench window is closed while my mapper is still alive. The crash happens some calls below the destructor of vtkShaderProgram2, due to an integer overflow in vtkGetOpenGLErrors. What happens here, apparently, is that glGetError doesn't stop producing error codes; probably because the program is destroyed after its associated context. Any ideas what I'm doing wrong here?
