[Bug}: When using pyimgui some users of my program have `GLError`s

[ajh123]

Not sure how I can reproduce the following error, anyway, some users (Linux with NVIDIA's X drivers) have the following error. I'm on Windows with the NVIDA's drivers and I cannot reproduce the error.

More information in https://github.com/obiwac/python-minecraft-clone/pull/104. The code in question is https://github.com/ajh123/python-minecraft-clone/tree/ui_rewrite/community. Currently I am not sure on the environment the user is running the program in.

Have you tried setting debug_gl yet? Here are my logs, but I don't think there's anything in there which can help debugging:

I can help debugging, I'm just a bit busy for the next couple days :)

@obiwac For me with pyglet.options["debug_gl"] = True I do not get any errors. Strange, isn't it?

[obiwac]

Indeed 🤔

I'll have a look then in a little while.

[ajh123]

[obiwac]

ah but have you tried this without your changes? i.e. in the main branch of mcpy?

[ajh123]

@obiwac In episode 12 (not modified) with pyglet.options["debug_gl"] = True I get no errors.

[obiwac]

yes but in community I mean

[ajh123]

Same results in community, no errors. Seems like NVIDIA's Windows and Linux (X) drivers behave very differently.
