           Summary: Polygons with parts outside the window gets misrendered.
           Product: Mesa
           Version: CVS
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Drivers/DRI/Unichrome
        AssignedTo: dri...@li...
        ReportedBy: uni...@sh...


Polygons which have parts outside the window will get misrendered with the
Unichrome driver. 

To reproduce, launch glxgears and resize the window so that a gear is partly
outside the window. Then the vertex coordinates that are outside the visible
area apparently gets clamped to the opposite border of the window, and the
triangle is drawn right across the window. Seems to be an easy thing to fix, but
I don't know where to look.
