Description 

The following bug report has been submitted:
Platform:        macOS-26.5.2-arm64-arm-64bit-Mach-O
ChimeraX Version: 1.13.dev202607102107 (2026-07-10 21:07:32 UTC)
Description
I left ChimeraX running for 3 hours, Mac Studio slept, when I came back the Mac would not wake so I pulled the display port cable and plugged it back in.  Then ChimeraX was on the display with the glClear error message.

Summary: ChimeraX bug report submission → OpenGL "invalid framebuffer operation" in glclear after display reconnected

comment:2 by Tom Goddard, 20 hours ago

When I subsequently try "graphics restart" I get the same glClear "invalid framebuffer operation". I tried graphics restart 5 times and always got the same error. So it seems the ChimeraX OpenGL context is broken.
