[Freesurfer] Misaligned datasets with identical headers in Freeview

External Email - Use Caution

Hi the FreeSurfer team!

I have generated two datasets with identical headers, but there is an offset between them when rendering them in Freeview bundled with FreeSurfer 8.0.0 and FreeSurfer 8.1.0 (Ubuntu 22 DEB releases in WSL2 on Windows 11 and on Ubuntu 22).

I did the same test on two workstations, and I had no issue when switching back to FreeSurfer 7.4.1 (Ubuntu 22 DEB releases in WSL2 on Windows 11).

It's unclear to me if it's only a rendering issue or if the CLI commands such as mri_segstats would also be impacted. I can send a private link to the test data.
