Hi Daniel,

I am working with a .las point cloud of 170 million points (4.4 GB), i am using v2.12.4 (Kyiv) on ubuntu 20.04, install trough flatpak.
After loading and automatic shifting, i apply a transformation (Ctrl+T) by inputing manually the 4*4 matrix.
Then after a minute CC just close.

I run on a 64GB RAM with 20 CPUs, when launching the transformation, i do not see any increment on ressource usage.
I can transfer the files if needed to reproduce the bug.

Well, I won't be able to reproduce the bug (I am not a Linux user myself) but I can double check that it's working at least on Windows (with version 2.13.alpha)...

Or you can wait a little bit more for the 2.13.alpha version to be available via flatpak (should arrive soon!).
