plot crashes using scf under Xubuntu

First I must apologize for my english, being far from fluent.

I am under Xubuntu 16.04. I have Scilab 5.5.2. As soon as I try to have several graphic windows using scf(), SCILAB doesn't work anylonger : it doesn't answer anymore.
I have another computer wich is an old Notebook. It's under Lubuntu 16.04. No problem to report. But it is so slow that I can't use it for my work. That's why I'd like to make SCILAB work under Xubuntu.
Is it a problem with Ubuntu or with ma drivers ? How can I fix it ?
Thanks for all.
