Cloud Loses Quality When Shifting

Pointcloud loses quality when its in its original position
here is what it should look like. And if I global shift to origin it stays like this.

But if I keep it in its original position it looks like this, even thought it still has the original amount of points. i can't save and re-import it with its original quality then.

I need to keep it in it's original position. Is there a way to view it in it original quality with creating the weird subsampling effect?

The second image shows what happens when loading too large coordinates (and a loss of information/accuracy indeed).

Maybe the shift (which can be derived from the internal LAS offset for LAS files for instance) may not be sufficient. Make sure that the local coordinates are small.

And the original coordinates are restored if you export the cloud to any format that support large coordinates (which is the case for most of the formats, but not all sadly).
