Using ViewCaptureToFile is glitchy, I have an image used as background in rendered display mode, and some 3d geometry in front of it, it also produces a strange kind of 4view result
Thanks @milezee I can reproduce this bug.
Here’s the YouTrack item: https://mcneel.myjetbrains.com/youtrack/issue/RH-50492.
This should be fixed in the latest RhinoWIP. Please give it a try.
