@sservice It looks to me like the theme isn’t loading quite right, so maybe it’s having a theme/font type problem. Possibly it’s looking for a certain font and when it’s missing it’s just silently failing. Some applications are only tested local from the system console, and need a bit of tweaking. The technique that I use in this case is to put in a few lines of debugging information in the script that calls this application and compare NX 3 vs NX 4. In this case I would check for fonts and for environmental variables. So, something like:
echo “DEBUG: fonts start here” > /tmp/nx4.log
xlsfonts | sort >> /tmp/nx4.log
echo “DEBUG: environmental variables here” >> /tmp/nx4.log
env | sort >> /tmp/nx4.log
Then just diff the two files.
