I’ve been using the Rhino Mac WIP version for a while and I keep getting the same bug using View Capture to File or Clipboard.
If I have the “transparent background” option ticked, the resolution multiplier set to above 1 and am exporting a parallel projection image to PNG, the background is offset by some amount, black colour appears and the image is ruined.
Easy to find a workaround for, but would be nice if someone looked into it.
There’s also another bug that happens when the transparency is turned off, but the resolution is turned to 2x. It sort of enlarges the image outside of its normal boundaries and crops it.
