This will solve it:
options.add_argument("--disable-3d-apis")
I should probably set that option to always be on.

This may already be fixed. Upgrade to the latest version of SeleniumBase and use --enable-3d-apis to activate 3D Mode from pytest, or enable_3d_apis=True from the SB() format. (3D Mode is disabled by default unless the option is set.)

There's also a new example test for displaying a 3D animation: SeleniumBase/examples/test_3d_apis.py
