[GRASS-user] 3D view error on MacOS (black screen)

[Anna Petrášová]

Hi Carlos,

I couldn't get 3D view working with homebrew either. The error you see
seems to happen when you click and drag in the window, so the actual
problem happens before, because it never loads. Interestingly, when I
compiled GRASS myself (using the homebrew libraries), the 3D worked.
Unfortunately I have no idea what's wrong.
