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.

Please try the ChimeraX daily build. I believe I made a change a few months ago to fix camera stereo. You are using the June 2019 release. If the daily build has the problem report again.
