GL context error on Linux

[oatsvine]

I build from the instructions and get this error:

During handling of the above exception, another exception occurred:

I can't see to build at all with python 3.10. This is from master at the time of writing.

[iamargelh]

use export PYGLET_SHADOW_WINDOW=0
and then python UVR.py

[RandomErrorkun]

use export PYGLET_SHADOW_WINDOW=0 and then python UVR.py

This worked for me, thanks~
