Hi Yufeng,
This is a problem with a recent graphics driver update from Intel on
Windows 10. So far it appears that the build series "4.5.0 - Build
24.20.100.xxxx" is affected. Can you please tell us what PyMOL reports
as "OpenGL graphics engine" (3 lines printed in log window on
startup)?
Luckily, there is a simple workaround, PyMOL has two different
implementations of the lighting model and only one is affected. Type
this into the PyMOL command line or put it in your pymolrc file:
set precomputed_lighting
Cheers,
Thomas
