@giannione: may you create a new bug report? I guess you don't have the same configuration as me, maybe not the same bug then.
Before doing that, may you check if you also have the problem with other applications using libvte? Pick one from: $ apt-cache rdepends libvte-2.91-0 libvte-2.91-0 Reverse Depends: mssh xfce4-terminal xcfa vinagre tilda termit synaptic sakura nemiver mate-terminal qemu-system-gui lxterminal lilyterm libvted-3-0 gtkterm gnome-color-manager gnome-builder giggle-terminal-view-plugin deepin-terminal cairo-dock-terminal-plug-in anjuta aghermann remmina gnome-terminal libvte-2.91-dev gir1.2-vte-2.91 and: $ apt-cache rdepends libvte9 libvte9 Reverse Depends: stjerm libvte-2.90-common python-vte rasmol libvte-common libvte-dev geany I remember I checked with geany and I also had the bug.
