Mi cliente xpra local es
t@ocean:/u/l/jvm$ xpra --version
xpra v3.0.7-r25627
Un xpra remoto (¿servidor, cliente o ambos?) es
t@ocean:/u/l/jvm$ ssh t@onion
t@onion:~$ xpra --version
xpra v3.0.8-r25889
t@onion:~$ logout
Connection to onion closed.
Tanto el local como el remoto ejecutan Lubuntu 18.04.
Gracias.

Después de actualizar la versión local de xpra para que sea la misma que la versión remota de xpra,
sudo apt install xpra
el problema desapareció.
