Pictueframe image scales incorrectly when not selected

When the pictureframe object is not selected the image scales to 50% of its size with the center point in the middle if the screen. Fine when the object is selected.
Background bitmap does a similar trick when zooming.
And printing crops to 1/2 size when raster is selected.
I have looked at all the help I could find - changed Nvida settings both in Rhino and Nvida
Latest Rhino 5 Dell Precision 5510 Win7 with 4K screen (does same if set to 4k or 1080p)
Guessing it is to do with the 4k

Hi Andrew - what version of Windows are you using?


Hi Pascal, Windows 7 with all current updates. Also Rhino is fully up to date.

Pascal, any more thoughts on this? Do you think it is a Win7/hardware incompatibility and moving to Win10 might fix it?

Hi Andrew - I do not have a good idea IU’m afraid - is the video card driver up to date? Can you post a screen shot of Options > View > OpenGL page?



Updated all drivers just before first post.

Hm - driver looks old… are you sure you have the latest available from Nvidia’s web site for that card? Only once has Windows built-in checker ever actually got me the latest…


Still the same. Maybe the next stage is to download the ‘New Feature’ Version
