I'm using the generic binary downloaded from http://texmacs.org/tmweb/download/linux.en.html on Ubuntu 19.04. Just tested it on my home desktop and the same problem happened there too. It is also *very* slow to start up (2-3 minutes). 

I think it's the X11 version. It's not linked to Qt as it seems.
