--- Comment #3 from Séb sebastien.fievet@free.fr 2009-06-20 15:40:16 --- If i correctly did the regression testing, the "bad" commit should belong to Stephan Dösinger :
[b2f09fd20421d0a5e179b42332ca63bc5ac17d8a] wined3d: Emulate clipplanes in ARB if the NV extensions are not available.
Hope this helps!
