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.

OpenGL renderer: llvmpipe (LLVM 7.0, 256 bits)
OpenGL vendor: VMware, Inc.
