There was an OpenGL graphics error while starting up. This is usually a
problem with the system graphics driver, and the only way to remedy it is to
update the graphics driver. ChimeraX will probably not function correctly with
the current graphics driver.

An error occurred in drawing the scene. Redrawing graphics is now stopped to
avoid a continuous stream of error messages. To restart graphics use the
command "graphics restart" after changing the settings that caused the error.

Appears to be inadequate graphics driver giving an error on startup on rather old 2012 graphics and Windows 7.
