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.

This has been reported several times, always with Linux and VMWare driver using Mesa with llvm. Not sure if it is a graphics driver bug. Could be related to the problem where OpenGL context becomes invalid after sleeping. Saw it in a windowsize bug 3 years ago related to the window not being shown due to rapid access on top of window.
