I'm running Thunderbird on a remote server. Whenever I click on a dropdown menu, it takes about 30 seconds for the application to respond. I can't tell if the delay is in sending the mouse event or in displaying the menu.

This does not happen when clicking on buttons (like Print or Reply), but only when there is a dropdown, like ReplyAll or the settings dropdown, or in the menus in a composition window.

I don't notice this delay with other applications. There is no delay when I run Thunderbird remotely using "ssh -X".

The server is running CentOS 7, kernel-4.15, x2goagent-3.5.0 x2goserver-4.0.1

The client is running Fedora 27, kernel-4.15, x2goclient-4.1.1.
