Only upper half of an inserted text displayed in V6

In V6 only the upper half of letters and numbers of an inserted text is displayed when using Dimension/Text Block; the file prints correctly, however.

Hello - can you please run the command SystemInfo (Help menu > System Information) and paste the results here?

Are you running in a virtualbox?


Right, you probably have to ensure that you have proper drivers installed for your GPU - currently Rhino falls back to the most basic OpenGL it can find, but unfortunately that doesn’t support all the drawing functionality needed. What kind of GPU is in your machine?

MacBook Pro (13-inch, Late 2011) with Intel HD Graphics 3000. I
reinstalled Rhino V5 which runs fine making illustrations.

As I understand it there is indeed no real solution. The problem arises on machines that were upgraded to Windows 10. The hardware is OpenGL 3.3 but Windows 10 transforms it into OpenGL 1.1 See
