OpenGL version: 3.3.0 - Build 20.19.15.4454
OpenGL renderer: Intel(R) HD Graphics 520
OpenGL vendor: Intel

[Tom Goddard]

Appears to be inadequate OpenGL 3.3 producing an error on glGetIntegerv(GL_MAX_RENDERBUFFER_SIZE). This may be an Intel graphics bug since the context is OpenGL 3.3 and this call is supported from OpenGL 3.0 on. Or it may be that some previous OpenGL error was not detected until this call and the error is misleading. Another possible problem is that this is Windows 7 which we do not officially support or test on. Also this is an old ChimeraX 0.7 version.

Since we do not support Windows 7 I will not try to test on a similar machine. I suspect it is driver related so in any case.
