[Elecraft] Strange Behavior on P3

[W4IEN]

My P3 has started to exhibit some strange behavior since I installed the SVGA and TXMon options.  Every time I turn the VFO A the P3 acts like it is being overloaded and the display shows interference.  I have never noticed this before.  Has anyone seen this behavior before?  I am running a K3S with the P3.
