I got this error with pyglet 1.4 on a new raspi 4 with raspian buster: Traceback (most recent call last): File "/home/pi/.local/lib/python3.7/site-packages/pyglet/__init__.py", line 353, in __getattr__ return getattr(self._module, name) AttributeError: 'NoneType' object has no attribute 'Sprite'
During handling of the above exception, another exception occurred: Traceback (most recent call last): File "./pyglettest.py", line 66, in <module> class Picmove(pyglet.sprite.Sprite): File "/home/pi/.local/lib/python3.7/site-packages/pyglet/__init__.py", line 359, in __getattr__ __import__(import_name) File "/home/pi/.local/lib/python3.7/site-packages/pyglet/sprite.py", line 109, in <module> from pyglet.gl import * File "/home/pi/.local/lib/python3.7/site-packages/pyglet/gl/__init__.py", line 237, in <module> import pyglet.window File "/home/pi/.local/lib/python3.7/site-packages/pyglet/window/__init__.py", line 1889, in <module> gl._create_shadow_window() File "/home/pi/.local/lib/python3.7/site-packages/pyglet/gl/__init__.py", line 209, in _create_shadow_window _shadow_window = Window(width=1, height=1, visible=False) File "/home/pi/.local/lib/python3.7/site-packages/pyglet/window/xlib/__init__.py", line 171, in __init__ super(XlibWindow, self).__init__(*args, **kwargs) File "/home/pi/.local/lib/python3.7/site-packages/pyglet/window/__init__.py", line 642, in __init__ self._create() File "/home/pi/.local/lib/python3.7/site-packages/pyglet/window/xlib/__init__.py", line 265, in _create self.context.set_vsync(self._vsync) # XXX ?

MESA_swap_control is required for this functionality. The output of glxinfo looks mostly similar to my ubuntu 18.04 desktop. Any idea how to fix this? Or is this a raspian-bug?
