Hi - if this is with the camera widget turned on and navigating with Ctrl+Shift, then this is a known bug (RH-49751 - is not visible to the public). If your workflow is different, please let us know.

(I’ve changed the category from Grasshopper to Rhino for Windows as I don’t see how this is related to Grasshopper)
