apitrace
I attached an apitrace for easier debugging purpose.
Looks like Blender picked a visual with no accumulation buffer for some reason, then tried to use it. We advertise a few with accumulation buffers, so I'm not sure why it didn't pick one of those. That said, accumulation buffers are going to be terribly slow (software rasterized, IIRC) on i965, and that's not likely to be fixed any time soon. It would be great if Blender would move away from these legacy GL features... -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
