Hi,

It seems the proposed solution with QVTKWidget3 posted on stackoverfow [1] that you referenced would work. Why not use this one? > If anyone else has some insight about problem with integrated cards > Qt 5 and VTK 6, I will be delighted! Last week I came across a shader compiler problem on Intel that that could be fixed by changing the shader code [2], but I guess that is unrelated.
