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.

You reported this same error 5 months ago, ticket #1888. As explained in that ticket your VMWare OpenGL driver is buggy. We don't recommend using virtual machines for running ChimeraX because their OpenGL support is poor.

[victoria.ruizserra@…]

Sorry, I'm not using a VM to run ChimeraX. I'm running it from my
workstation with Linux.

Ok. The graphics driver ChimeraX reports using is

OpenGL version: 3.3 (Core Profile) Mesa 19.0.8
OpenGL renderer: llvmpipe (LLVM 8.0, 256 bits)
OpenGL vendor: VMware, Inc.

A bug in this graphics driver prevents ChimeraX from working correctly. You would need to update your graphics driver in order to have ChimeraX work correctly.
