The transparent object object should be rendered correctly even if the display grid overlap it.

workaround : disable the depth peeling by pressing p fix that.

I reproduce the issue with the CompareTransmission.gltf data.

Also it looks like it depends on the camera's angle, I'll check the depthpeeling algo in vtk.
