QScreenRayCaster depth of ray adjustable? appears limited to < 50,000

[uani]

QScreenRayCaster does hit mesh which is 50,000 units away (distance along camera view axis) but doesn't deliver the correct worldIntersection. For 15,000 units distance it does hit and delivers the correct worldIntersection.

I would need a distance / depth of ray of 1,500,000.

Alternatively the ray starting position may be offset from the camera by ~1,499,999 :)

Can I achieve this? How?

appears to be a single precision floating point issue, as used by Qt3D internally
