[X2Go-User] Matlab in X2go

[Thackeray, Neil L]

I'm having some issues using Matlab2018a in X2go. When using xfce4 (and KDE) desktop it causes some exception when the X2go window is hidden or resized. It also will hide all of the button widgets in Matlab until I mouse over them.

When I change the session type to 'Single Application: Terminal', and then typing 'matlab &' in the terminal it works perfectly fine.

This is the exception that Matlab throws, usually many times:
