I’ll suggest a couple of things - (1) you are using a development build of freesurfer which could be unstable. I would instead try the most recent 7.4.1 release for Ubuntu, and install it via the .deb file installer (system updates may be needed), which you can pick from the downloads available under MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/rel7downloads. Just “sudo apt remove freesurfer” and then “sudo apt install ./<freesurfer deb file>”. (2) Perhaps something is going on with OpenGL drivers and graphics hardware. You could check the latest OpenGL drivers are installed and what you are running is compatible with your version of Ubuntu Linux.

- R.

External Email - Use Caution
Hi all,

I am encountering the following issue: In FreeView, when I use the mouse to navigate, the crosshair is not under the cursor, but about an inch left and down from it. When I resize the FreeView window, it starts to tear. See the attached screenshot or the Github issue that I opened here: MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://github.com/freesurfer/freesurfer/issues/1129

My environment:
OS: Ubuntu 22.04.3 LTS (but this happened with 20.04 as well)
FreeSurfer: freesurfer-linux-ubuntu22_x86_64-7.4.1-20230614-7eb8460
FreeView: 3.0; Build Jun 14 2023 03:48:54 (but this happened with previous versions as well)

Best,

Vincent
