Hi Dennis,

That is bad news, but note that the official releases are still based on Qt4;
the Qt5 version is currently in a test phase. Could you give us more details
on your system and what version of TeXmacs you are using (do you use some
pre-compiled binary or did you do the compilation yourself)?

Best wishes, --Joris
