Oh I see, Y coordinates rounded into 0 or 0.5 (6106507.6058830 is rounded into 6106507.5000000) when exporting from LAS into PCD which is why it causes those lines. Do you know how to resolve this problem?

Yes, refer to my very first answer: PCD files can't store large coordinates (as they are limited to 32 bits floating point values). You are bound to shift the coordinates (which means in effect sayinig "Yes" to the Global Shift dialog, while unchecking the ""Preserve global shift on save" checkbox.

But of course this means that the coordinates in the PCD files won't be the same as the original LAS file...
