I've seen this too and went as far as bisecting Mesa: <https://bugs.freedesktop.org/show_bug.cgi?id=110608>. ...after bisecting Guix to e6a668ec7303a71f87e4c9354b1458e555058c63. (Guix makes this process surprisingly easy btw, someone should write a blog post about it.) The fix is to wipe Mesas shader cache: $ rm -rf "$HOME/.cache/mesa_shader_cache" You may also need to do the same for your display manager, if any: $ sudo rm -rf "/var/lib/{sddm,gdm}/.cache/mesa_shader_cache" I don't know why Mesa fails to do that on its own. I can't find a lot on the internet about this issue, so I suspect it is a problem specific to Guix.
