Depth buffer description
* width is 10 pages
* texture/scissor size is 640x448
* depth is 16 bits so it writes 70 (10w * 7h) pages of data.
following draw calls will use the buffer as 6 pages width with a scissor
test of 384x672. So the above texture can be seen as a
* texture width: 6 pages * 64 pixels/page = 384
* texture height: 70/6 pages * 64 pixels/page =746
So as you can see the GS issue a write of 640x448 but actually it
expects to clean a 384x746 area. Ideally the fix will transform the
buffer to adapt the page width properly.
