Comment (by dwatteau):

 One interesting thing, is that on macOS 15.7.2 (still running on an M1),
 running the demo again now outputs this warning:

 {{{
 UNSUPPORTED (log once): POSSIBLE ISSUE: unit 0 GLD_TEXTURE_INDEX_2D is
 unloadable and bound to sampler type (Float) - using zero texture because
 texture unloadable
 }}}

 Some quick online searches for this seem to confirm an OpenGL
 bug/limitation on M1:
