Looks slightly unnatural :-). The fog code in this driver looks like it could need some cleanup, it seems to have degenerated a bit. There are for instance references like this: /* Hack: make sure fog is correctly enabled according to this * fragment program's fog options. */ except if you look at the function call it's a no-op nowadays... As far as I can tell the whole i915_update_fog function is basically obsolete since the appending of the fog in the fragment program. Not sure though, hw fog might still get enabled if this is called before the update of the fragment program (which would add a bogus fog calc in addition of the correct one probably). So, could you try never setting S5_FOG_ENABLE in i915_state.c? You can just comment it out. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
