Summary: ChimeraX bug report submission → Capturing thumbnail image: Attempt to retrieve context when no valid context

comment:2 by Tom Goddard, 3 years ago

Resolution: → can't reproduce
Status: assigned → closed

Capturing an image made the graphics context current without errors, but then glVertexAttribPointer() call claimed there was no current context. Maybe a driver problem. I recall an OpenGL context can in rare cases become invalid, maybe for example when the user connects an external display and closes the laptop lid and the display is now being driven by a different GPU. Never found out if this really happens. Would not be too surprised on Linux.

Aha, this is also on Wayland. I thought our ChimeraX 1.4 detect Wayland and set an environment variable to use X11 emulation.
