Cannot activate or deactivate OpenGL from Preferences

[nroduit]

In some situations, it may be advisable to disable OpenGL support, or the prerequisites may seem sufficient, but in reality opening the 3D viewer may cause the application to crash (e.g. with VirtualBox).

Re-enabling OpenGL from preferences doesn't work.

As a workaround, you can modify the following properties from the file ~/.weasis/data/weasis-core/persistence.properties:

opengl.enable=false
opengl.prev.init=false
