Just done some online testing regarding this as its not really happening in the stock version
Apparently rendering of some "franken planes that are used be it AI or human can cause the problems,
the log files may show errors related to aircraft usually modded beasties, even some load outs were affecting warping rubber banding.
One of the biggest results was people flying outside the cockpit and or scrolling around other aircraft and returning to thier cockpits,
this can cause problems too in the presence of modded aircraft.
