This is because DM places offsets the cursor for primary planes only to workaround missing code in DCE for the adjustment we're now correctly doing in DC for DCN ASIC. [How] Drop the adjustment for source rect from the DM side of things and put the code where it actually belongs - in DC on the pipe level. This matches what we do for DCN now.
