Not sure, then, but maybe it was run one time as superuser???

I just tried mine, it doesn't show Superuser, but I'm only showing 20.12 
for reason, I thought I had 22.something on here...Well, just grabbed 
23.12 source, compiled and run... still doesn't show as superuser.

Just tried running it as superuser via sudo rosegarden - still no sign 
of "superuser" in the terminal title...

I'm running Debian 11 with the XFCE desktop. Maybe it's something 
connected with your distro/desktop environment???
