I don't reproduce this issue, using Guix 9f4b6bc with IceCat version
102.14.0-guix0-preview1, although I must *not* set LIBGL_DRIVERS_PATH
the way you did otherwise it fails.
I'm using an nvidia 8800 GTS card with the nouveau driver, and the
spinning cube displays fine at https://get.webgl.org/.
Is it still a problem for you?
