The problem is already bisected. The commit that introduces the regression
switches nv50 to use nvc0's disp implementation. The commit is basically
deleting all the nv50 code and changing a few function pointers to use the nvc0
implementation. I tried pin pointing what the problem was (see <a href="show_bug.cgi?id=67878#c34">comment 34</a>) but
I was not able to fix the problem.</pre>
