Problems with imported PDF file in R6

Hi everyone.

I Just imported a PDF file without any problems.

But the issue is if I drag it, it will be all white, if I drag it again I can see the drawing, and if I drag it agail it turns all white again.
It keeps going like this. Every second time I drag I can see the drawing, and every second time I drag it turns all white again ?

Can anyone help me ?

Regards Jan

Hi Jan - can you please run the SystemInfo command in Rhino and paste the results here?

Hi Jan - it is more useful in this context to use the Rhino command SystemInfo.

Hi Jan - thanks - I do not see any red flags - the video driver is getting maybe a little old, it would not hurt to get the latest from Nvidia’s website and see if that sorts anything out. Does the problem occur in any display mode?


Which is the Rhino 6 SRx you are using?

It’s working for me.


Hi Pascal

It´really weird.

After running the systeminfo I just tryed to import the same PDF (which I did many times before), and now it works perfect !

Don´t know what happened, but thanks for your help anyway.

Regards Jan
