I was wrong in the review #167 (review) to think it is ok to set vertex size to an illegal value. It is not because it may result into memory error. I think it is implied in the qt3d doc: https://doc.qt.io/qt-6/qt3dcore-qattribute.html#vertexSize-prop.
I will file an issue to track it. The vertex size may be an important parameter for qt3d and I do not fully understand its meaning.
On my macos, using 5 causes wrong rendering of the lines.
