Does that bug a have bug report somewhere? Do we know if it’s still not fixed?
The bug was reported to Nvidia. Presumably, there is a bug report in the non-public Nvidia bug tracker. The bug is still not fixed. The viewport subpixel bits quirk is activated only when the bug is detected, see match_broken_viewport_subpixel_bits() in wined3d.
