Did you remove an external display during this ChimeraX session? That is the only idea I have about this graphics error could happen.

You might want to update ChimeraX to the current version 1.10.1. You are currently using ChimeraX 1.8 which uses an older version of the Qt window toolkit and the bug may have been fixed in newer Qt versions.

ChimeraX got an OpenGL invalid framebuffer error in an expose event trying to draw the status line. The code has already made the OpenGL context current successfully so it is unclear how this can happen. It seems like either a Qt window toolkit bug or Mac OpenGL graphics bug.
