Dual cursors happend in virtual desktops

Recently we encountered a problem that two mouse pointers displayed when dragging application window in Windows OS in vdi environment.The remote one always moves behind the local one.It’s teradici’s PCoIP protocol we use and it happens in both vmware vSphere and openstack virtualization platform no matter passthrough or vGPU.But the standard desktops without graphic cards don’t have the problem.
Anyone helps me,thanks a lot.
