I have a simple scene with a disk that covers all the screen. The disk use a constant shader. The final render must be a white screen, but the fist row and column is grey. It looks like the disk have a border in these row and column. I attach two ribs. The first has the error. The second is the same scene with a different translate values but It's rendered fine.

    The clipping volume test is culling geometry needed during the sampling process. The uploaded patch modifies how is the clipping volume calculated.It calculates a frame extension for the screen window that includes pixels used during the sampling process. This new frame limits are used tuo calculate mew frustum planes for the clipping geometry test.
