Hi, Brian!
First of all, welcome to X2Go! You're actually the third NASA employee hitting our list (the other two were from JSC-EG311 and JPL-392K). Sorry, that doesn't mean you've won a prize. ;-)
Some things I would like to ask you to do/try:
Please let us know the name of the software that has these issues with X2Go; if it is non-free and/or something NASA developed internally, you might want to get the developers of that software involved as well so they can talk to ours. Screenshots would help, too - but please remember to black out confidential information that might be visible on it.
Please try different slider settings and image compression algorithms in the connection settings. Maybe it only affects JPG, or only PNG, ...
Also, please try running the software with X2Go in single application/published application mode (IOW, rootless mode) vs. fullscreen/windowed mode. This is becahse parts of the screen drawing process work differently in rootless mode.
If you have a chance to run this software along with X2Go in a separate testing environment, you could try following these steps and see if it changes anything - but please do not do this on a production system: http://wiki.x2go.org/doku.php/doc:howto:nx-libs-betatesting (Note that at present, this probably only works for Debian-based distributions, not for Redhat - but if you have a test lab available to you, you could "ssh -X brian@redhat-test-box" from the Debian box within the X2Go session.)
We'd love to hear how you use or intend to use X2Go, so we can publish your testimonial on our success stories page in the wiki. Since you seem to be working with weather satellites, that sounds like a rather interesting use case for X2Go.
Last, I hope you don't mind that I mention this ...
<shameless plug> X2Go also has a commercial side, where various companies - including my own - offer support contracts with guaranteed response times as well as consultancy and paid-for development work if someone wants to see a bug fixed or a new feature added in a certain time frame. What makes my company special is, IMHO:
- I'm the current X2Go Project/Community Coordinator, so the development lead and the developers tend to listen to me.
- As far as I know, we are the only company providing X2Go support that isn't a one-man-show.
- We sub-contract other developers from the X2Go community on demand, so you only have one person you need to talk to - me - and you will only receive one invoice, even if the task involved several freelance or part-time X2Go developers.
Our hourly rate for consultancy work and fixing issues outside of a support contract is 110 EUR. With a support contract, you get guaranteed response times (starting at 400 EUR/month for 24h response time during business hours in the CET/CEST time zone from Monday to Friday, German holidays excluded) and lower hourly rates if you buy a certain amount of hours in advance. </shameless plug>
Kind Regards, Stefan Baur

Package: x2goclient
Version: 4.0.5.2
Connecting to remote RHEL system using x2go has color issues with certain panels of an application on that system. When connecting via NoMachine the panels show up as they should, black background, white text. However with x2go the panel shows up as a grey background with black text, and some text are just black boxes (the major issue is the black boxes obscuring text).
I noticed a bug along these lines from back in 2013 (#262 ) (http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=262)
