I ran into this same issue with ITK-SNAP ver 3.8 when using Windows Remote Desktop to log into Windows 11 server, but when I log into the computer directly, I am able to view axial, coronal, & sagittal views as well as scroll through images properly. Also, when I use VNC to connect to the server rather than Remote Desktop I am able to use ITK-SNAP properly as well... so this seems to be a Remote Desktop issue.
