I am new to Rhino. Recently installed v6 on my Win 7 Pro desktop. I am following some basic YouTube tutorials. When I draw a simple rectangle on the Top viewport, I see it created, but the Perspective viewport fails to update, and in fact, as I toggle from Rhino to my browser and then back to Rhino, (some of) the viewports will display the content of the browser that had been showing when the browser had focus. I have tried various resizing options of the Rhino screen, but the viewports fail to display what should be exclusively Rhino renderings.
Machine performance is basically idling @ 10% of memory used and CPU @ 0.1%
Hi @jmc
Run the SystemInfo command in Rhino and copy/paste the result here - but as @Lukas_Mateja mentions, there’s a good chance an updated grahics driver will help.

I have at home also an old Radeon HD, just a bit newer than yours (7xxx series). We have tried many, many, many things to get Rhino working on it, but this old series 7xxx and before, including your 4800, just refuses to work well with Rhino. I am afraid Rhino 6 (and Rhino WIP) will not work properly on these GPUs
