Description Javier Jardón 2016-02-10 15:57:26 UTC
This makes gnome-shell to crash, because Xwayland depends in dri3 now:

14:55 <daniels> strictly:~% LIBGL_ALWAYS_SOFTWARE=1 gnome-shell --wayland   
14:55 <daniels> Disabling glamor and dri3, EGL setup failed
14:55 <daniels> Failed to initialize glamor, falling back to sw
14:55 <daniels> strictly:~% gnome-shell --wayland                     
14:55 <daniels> glamor: EGL version 1.4 (DRI2):
Comment 1 Michel Dänzer 2016-02-12 03:41:57 UTC
Note that Xwayland (and by extension gnome-shell) should work perfectly fine without glamor/DRI3, so fixing the crash should be significantly easier than making glamor/DRI3 work with swrast.

yes I don't think this bug has been diagnosed except via handwaving yet.

Though it does appear mutter is crashing inside glClear after my 5m of investigating.

However further investigating is blocked on some llvm build problems in rawhide that I'm trying to clear first.
