1871	Graphics window gray after first model opened.	goddard@…	Tom Goddard	"{{{
The following bug report has been submitted:
Platform:        Darwin-17.7.0-x86_64-i386-64bit
ChimeraX Version: 0.9 (2019-04-17)
Description
Starting ChimeraX and opening a map (emdb 1080) showed only a gray graphics area.  An error to the terminal where I started indicated that graphics had been halted due to an error, apparently at startup.  This happened to several people at today's ChimeraX demo.  Probably it is a race condition, maybe more likely to happen on faster machines.  People at the demo restarted ChimeraX and got it to work.

I got this one time but could not reproduce in 5 more tries.

BUG: 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.

Traceback (most recent call last):
