Lines and curves don't show up after updated Rhino 6 version

Hi there,

after I’ve updated the rhino 6 file i cant open illustrator files properly anymore as the curves and lines wont show up. when I try to draw on a new file they wont show up either.
I’ve tried restarting the program and ticking und unticking GPU tessellation but it doesn’t change anything.

Please help is there enything i can do?

Run the V6 “SystemInfo” command and post the results.
I suspect you have old drivers causing problems.
