Missing elements in Raycloud editor

All functions/views are working fine in Pix4D except the RayCloud Editor - after initial processing when I go in this viewer, I get grey boxes, no main view and missing photos on the right.  

Video card issue? Any thoughts?

Hi Mike,

We would first recommend to download our latest stable version 2.1.58: https://mapper.pix4d.com/download/

Then could you tell more about the GPU model and its driver version?

This was indeed a video card issue - I’m unable to get the specs easily because it’s on an offsite dedicated AWS.  We found a workaround using TeamViewer to connect instead of RDP which seems to fix the issue.
