[Eric Pettersen]

There is also a "time data does not match format" error in registration.

[Tom Goddard]

The OpenGL man page for glDrawBuffer suggests GL.glDrawBuffer(GL.GL_NONE) cannot generate invalid operation. Possibly it means no OpenGL context is current. ChimeraX called make current and it did not fail, but perhaps it did fail and yet Qt said it was successful. Maybe the window was not mapped because recent files were still shown. No way to debug this unless I can reproduce it.
