ViewCapturetoFile - exports repeating fragments?

When I try export using ViewCaptureToFile - i set the resolution to 3200x2400 and I get this half cut off export. The higher the resolution - the more repeats.
How do I fix this?

That looks like an issue due to the GPU, display mode and the image size. Try the Export command instead and choose PDF as the format. You’ll need to select the objects but you can then still set the large image size you need.
