I am using PuTTY to do SSH tunneling and X11 Forwarding with an Amazon EC2 Ubuntu instance. Multiple individuals in my system login to their own remote desktops, and then connect to the same EC2 instance.

I am currently trying to fix an issue where half of the screen is cut off for some users after the forwarding. I've tried

1) Make sure everyone uses the same network, however this doesn't solve the problem, the full screen shows up for some users and only a cut off screen for other users

2) Logging into the remote desktop of the users who are experiencing the cut off screen problem (using my own laptop), however I'm not able to replicate the issue

3) Configure the Xming display settings in XLaunch, and have Xming display in one window instead of multiple windows. Jury is still out on whether or not this works, I haven't had the users try out the new configuration yet. Also, when I open save XLaunch configs, hit finish, and then later open up XLaunch again, "multiple windows" / default settings are selected, rather than "one window". So before I tell users to try out the "one window" setting, how can I make sure that my new configurations are actually saved?

4) Do the PuTTY connection and X11 forwarding set up through XLaunch, rather than through PuTTY. I think this would be rather complicated so haven't tried it yet... though willing to do so if it could solve the issue.

Thoughts? Image of the problem is shown below.
