When in Rendered Mode and using Capture Viewport to File (or Capture Viewport to Clipboard) some Materials become Transparency. In Raytraced Mode, there is no issue. The issue only happens, when “Transparent Background” is turned on. When turned off there is no problem. Independently of material type, white Materials (100% White) do not have the issue, and dark/black materials become transparent. Changing to Material Type Custom solves the issue. However, I can not change all Material types, as I am working with a shared Material Library and Block Instances that already have Materials applied that I can not change.
The issue seems to only occur on my PC, as colleagues can open the file(s) and do not come over this issue.
See attached screenshots and the Rhino File with some Materials and System Info.
