This seems reproducible on rv250 too (never noticed it before...). Note that it's completely independent of the fog settings, so I'm not sure what's going on. It reminds me of some bugs though we fought a lot a long time ago, which were solved by using a fixed ordering of emitting state atoms - the more correct solution finally was to write to the RADEON_SE_TCL_STATE_FLUSH when emitting certain tcl state. Maybe those tcl flushes still don't quite happen always when necessary, it isn't well understood really when exactly that's necessary.
