turnip: LRZ should not be disabled when compare_op is always but depth_fail_op is keep
case VK_COMPARE_OP_ALWAYS:
/* nothing to do for LRZ, but for stencil test when stencil-
* write is enabled, we need to disable lrz-test, since
* conceptually stencil test and write happens before depth-test.
*/
if (stencil_write) {
return false;
}
break;
IMO stencil test results are same after LRZ when compare_op is always and depth_fail_op is keep
