OpenGL error messages (in debug mode) when closing an mdichild #26

Closed codeling closed 5 years ago

codeling commented 6 years ago

When open_iA is compiled in debug mode, and one closes an mdi child window, the console shows several OpenGL error messages like this: 

ERROR: In vtk\src-7.0.0\Rendering\OpenGL\vtkOpenGLTexture.cxx, line 94
vtkOpenGLTexture (000000000B1EB760): failed after ReleaseGraphicsResources 16 OpenGL errors detected

This bug started when the 3D magic lens was introduced to the general renderer window. A fix probably needs to involve migrating to the new QVTKOpenGLWidget instead of QVTKWidget2.

Fixed with the migration to QVTKOpenGLWidget (2018.12).
