the problem returned. I reinstalled GSX in hopes it will fix it
Since nothing in GSX has changed, and your last report clearly indicated the fix was acting of something else, it should be quite clear by now the problem didn't had anything to do with GSX, so you cannot expect it to be fixed by reinstalling GSX.
I wonder if the marshaller being 30 ft off the ground is what is causing the weird characters to appear?
If the marshaller altitude was off, the characters would be also off, not scrambled.
But, I never fully understood the weird things OrbX does with elevation, or why they have a need for an elevation correction tool in the first place (wouldn't be easier to simply not have anything to fix ? ), and the few times I inquired with OrbX about such issues, they never care to reply, although the *did* some fixes, for example at KLAS.
Of course, you can always decide to simply turn off the distance indications. However, if the issue is related to Simconnect, it's likely it will resurface again in other parts of the sim.
The easiest way to know if the issue is related to Simconnect being overflown with too many commands and thus not being responsive enough, is to temporarily disable ALL your addon modules in the DLL/EXE.XML files, *except* for the FSDT modules (bglmanx.dll in DLL.XML and couatl.exe in EXE.XML), and see if it makes any difference.
