this issue happens on G965 GM965
define 6 user defined clip planes as follow:
first enable CLIP_PLANE0, CLIP_PLANE1, CLIP_PLANE2 (with others disabled), draw a point at (10.5, 15.5, 0.1), this point should be clipped out, it does work well.
but then, disable CLIP_PLANE0, CLIP_PLANE1, CLIP_PLANE2, and enable CLIP_PLANE3
draw a point at (10.5, 15.5, 0.1), this point should not be clipped out. but it did clip it out.
this issue doesn't happen in non-DRI mode.
