Crashed in OpenGL rendering at

  File "/usr/lib/ucsf-chimerax/lib/python3.9/site-packages/chimerax/graphics/opengl.py", line 2704 in draw_elements

which is this line of code

            GL.glDrawElementsInstanced(element_type, ne, GL.GL_UNSIGNED_INT, eo, ninst)

This is a graphics driver crash. Using a Quadro 4000 released in 2010 -- it is amazing the driver works at all with such an old graphics card.
