Hi Dieter, Thanks for noticing this. I think I made a mistake by setting window_space_position the way I did. Should've only set that for vertex shaders.
I believe this is the right thing to do: https://gitlab.freedesktop.org/Venemo/mesa/commit/4d8b97bacbe14bd6584d7a45ff98e65dfcb4c02b Still need to test it myself. If it works, I'll submit a MR. Let me know what you think.
