So I made the leap and got GSX and GSX L2.  Installed fine, no issues.  Took each of my Delta Air Lines aircraft and configured them all for the ground servicing and tested all 9 aircraft to make sure everything worked.  Was amazed that I pulled it off.  My one and ONLY issue is with my A350.  During the passenger deboarding, the pax look like giant hot air balloons (see attachment) as they exit the aircraft.  Once outside the aircraft on the airstairs, they are fine.  This also happens when pax were using a jet bridge at any airport.

That's a problem with video settings, it's possible your are short on VRAM and/or some video tweak you might have applied to the FSX.CFG shouldn't be applied to your system.

The best to check if this is the case is removing the FSX.CFG file ( move it to a safe place, don't delete it, so you can restore it back ). When you remove the FSX.CFG, a new one with all default settings will be created automatically. To this new file, ONLY the HIGHMEMFIX = 1 tweak, nothing else.

Then, you will have to reinstall GSX OR (of you know how to do it), restore the Simobjects lines from your original FSX.CFG file into the new one, to add the ones that has been installed by GSX, otherwise it won't find any of its objects, resulting to errors in game. If you have other add-ons that added their Simobjects lines, add them too as well. Basically, all the Simobject lines from your original FSX.CFG should be restored in the new one.

Also, if you are using FSX SP2, there are still some bugs left unsolved which are SP2-specific, and don't happen with the Acceleration Pack or the Steam version so, if you are using SP2, I suggest switching to the Steam version if you can.

Turned out to be the aircraft itself.  Swapped out the TDS A350 for a lessor quality CamSim A350 and everything worked fine.  Really weird that an aircraft model would do that.

Not really weird.

A model with lots of textures might push the video card closer to VRAM exhaustion, and that might triggers weird issues and bugs in the sim, which would effect the passengers animation, which is based on shaders, which runs in VRAM as well.
