External Email - Use Caution
Sure thing. I'm not sure if my last email was sent as it contained images >
listserv allowable size, so I've reposted it here, hosting the images on
imgur.
I've tested it on 4 monitors, all at 2560x1440p native resolutions. An ASUS
PB278, an ASUS ROG PG278Q, a GIGABYTE M27Q, an an ACER XV272U. Here are the
mac display preferences testing each individually:

I tested with and without "Default for display" and "Scaled". Each time the
monitor was set to "Default for display" or scaled to 2560x1440p or scaled
to any resolution > 1600x900, FreeView seg faults at:
"
loaded library
"/Applications/freesurfer/7.2.0/Freeview.app/Contents/PlugIns/imageformats/libqwebp.dylib"
/Applications/freesurfer/7.2.0/bin/freeview: line 2: $NUMBER Segmentation
fault: 11 $FREESURFER_HOME/Freeview.app/Contents/MacOS/freeview "$@"
"
Not that I think it would make a difference, but for completeness, I also
tested jittering the refresh rate between 30 and 144Hz, and tested with a
USB-C-to-USB-C, displayport-to-USB-C, and HDMI-to-USB-C. Neither the
adapter nor the refresh rate made a difference in behavior.

After some feedback and some more testing, I can reproduce that
freeview.app in the 7.2.0 release will segfault on MacOS 11.4 if the
license file cannot be found or it cannot be read.. One user reported that
