newly installed on Lenovo Thinkpad, windows 10 with Nvidia card
SKUP loads perfectly yet I am unable to see images or any activity on graphics screen. menu, tool bar, and default tray display perfectly.
Make sure SketchUp is not using the integrated Intel GPU. Check in Window>Preferences>OpenGL. Go to the Nvidia site and make sure you have the latest drivers for the GPU.
Untick Use Fast Feedback and see if that changes anything.
Assuming that takes care of the issue, please take a few moments to complete the survey here.
