        a pre-existing issue, then it has gotten much worse recently.

I believe the behavior depends on the card.  Mine are 

01:00.0 VGA compatible controller: nVidia Corporation Quadro NVS 140M (rev a1)
01:00.0 VGA compatible controller: nVidia Corporation Quadro NVS 570M (rev a1)

Both are relatively new cards.  The nv driver didn't even detect them
properly when F8 came out.

(BTW, top posting is frowned on on this list.)
