Bug#881177: xdvi does not draw all the symbols properly

[Леон Майер]

After Debian stable switched to Wayland by default and texlive evolved from 
2016 to 2018.20181218.49446-1, I cannot reproduce this bug any more with xdvi. 
Evince also shows all the symbols. If you are still interested and tell me how 
to temporarily switch back to xorg, I with double-check with xorg then (but it 
is unlikely to happen anytime soon).
