unusual PCOIP mouse scroll behavior

I'm seeing some unusual mouse scroll behavoir when using PCOIP(TERA1)>worskstation(Centos6).  The windows jump around and the scroll resets/reverses erratically.  It seems to be related to any mouse movement at all during the scroll.  Happens in both KDE and Gnome.  It also does not occur when the mouse is directly connected to the computer so I don't think it is a function/setting. 

It appears with both local and remote cursor settings over PCOIP.  I'm getting 2ms latency so I don't think that would be the issue.

Has anyone else seen this type of behavior before?

Thanks!
