[chimerax-users] chimeraX silhouette show dark spots

Dear ChimeraX support team, I'm experiencing an issue with ChimeraX silhouette showing dark spots. I’m using ChimeraX version 1.7.1. Please see the picture attached. Could you please help me resolve this? I’m using the latest version of macOS Sonoma 14.4.1 (graphics: intel iris plus graphics; processor: 2GHz Quad-core Intel core i5) Is this a graphic issue? This could be a ChimeraX bug for the newest version of mac as my peers who are using an older version of mac do not have this ChimeraX issue. Thank you for your help, Kelly
