nVidia Dreamworks - RDP - small visual bug


We are using nVidia DreamWorks RDP OpenGL accelerator over VPN with various softwares, including ZBrush, Motionbuilder, etc., all running in OpenGL. We made sure to deploy the correct version of nVidia drivers, etc. We have a user who has a small glitch (visual corruption), as the mouse cursor is not visible / is replaced by a black square. Would like to know please if you may know how to fix this?

Would like to take a moment to say thank you for the development of this tool, it helps us a lot given the remote / work from home (COVID) situation.
