Try to use PyOpenGL with a higher version, ours is 3.1.5.

I have tried to upgrade the Opengl version to 3.1.5, but this error still exists, I hope to get other guidance. Thank you.

Hello, After I tried to add MESA_L_VERSION_OVERRIDE=3.3 in the running line, my page can be opened without error, but the page is still in the state of "waiting for ··". How can I solve this problem?

The print log is as follows:

@zhouliuling
i have the same problem, and add MESA_GL_VERSION_OVERRIDE=3.3, the problem was disappeared.
But got another problem:

OpenGL.error.GLError: GLError(
err = 1286,
description = b'invalid framebuffer operation',
baseOperation = glClear,
cArguments = (16640,)

have u worked it recently?

I have solve the problem, the point is vnc server OpenGL connot connet to Nvidia, i google so many times but never solve the bug.
so u need to run it on your local host, and everything is OK.

i run ok, but the web shows nothing, and "my render" windows show nothing
