Viewports misbehaiving

I’ve recently got a new computer and rhino viewports are not working properly, sometimes the top view is in the right viewport and the rightview in the top perspective window. They just keep jumping around. I have windows 7


HI Deborah,

I suspect you have an AMD gpu (video card). This is a known issue with out-of-date drivers
Try updating the AMD drivers and let us know if the problem persists.
