AttributeError: 'NoneType' object has no attribute 'glActiveTexture'

Rasp Pi 4 on Buster. Up to date, fresh install

When trying to run any of the demos I get

Traceback (most recent call last):

This looks like the same error as before in https://github.com/tipam/pi3d/issues/214

Is this due to the type of driver set up in raspbi-config? I will see if I can reproduce this error.

I've got the same issue on a Raspberry Pi 3b using Raspberry Pi OS current version as of 2/26/22

Away at moment but will do some tests when I'm back. Also with 64 bit version

I have the same error on a fresh PI OS install and update with snake eyes from adafruit.

Thanks @Jacques-Olivier-Farcy,
In case anyone else comes across this thread - it seems to be related to the changes in RPi graphics driver. You can see discussion and solutions helgeerbe/picframe#195 (comment)

However the OP does say they are using original buster OS which hasn't loaded the OpenGLES library correctly. Not sure if this is fixed or not as I haven't reproduced it.

Hi there,
Yes i can confirm that with the Buster image of raspios and after a (long) update / upgrade, it is working fine.
I used PI OS [raspios armhf buster lite](http://downloads.raspberrypi.org/raspios_lite_armhf/images/raspios_lite_armhf-2021-05-28/2021-05-07-raspios-buster-armhf-lite.zip.torrent
