glBindFramebuffer raise GLError 1280

[INFO-studio]

Describe the error

When i run manimgl xxx.py xxx everything is good and when there's only code self.wait() and run manimgl xxx.py xxx -w it will be fine too, but when my code add some mobject in the output screen and run manimgl xxx.py xxx -w or manimgl xxx.py xxx -o, it raise GLError 1280

Code and Error

Code:

from manimlib import *

class S1(Scene):
    def construct(self):
        c = Circle()
        self.wait()
        self.add(c) # error

when i remove the error code and it will run perfectly(but i can't do nothing)

Error:

Well, I found out what the problem is, just add a line gl.glGetError() to function get_raw_fbo_data in file /Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/manimlib/camera/camera.py and it will be solved. (File locations may change depending on the system environment)

It still doesn't work. I tried doing this and it works when i pass argument -w but normally it doesn't.

Please show me as many error messages as possible when you try to rendering normally, that can help to determine where to modify the program.

[Shekhar-Dangi]

Yeah, this is what I got :

In the error messages, you can find which file and which line raised this error from the bottom to the top, just add gl.glGetError() before this line. And if that won't work, try another error message until it will. XD

@INFO-studio Thanks a lot.

@INFO-studio seems that it works for me, could you help explain why this can fix the issue? Since it is just get the last error from OpenGL

Well, I guess that's just because some non-fatal errors happened, which I didn't find why. OpenGL can just draw it and continue working, but when the code start to clear the cache and prepare to write the next frame, the error was still in the todo queue and OpenGL will stop the script and draw error. That's also why it can work in preview mode(because that needn't to clear the cache).
