Tearing while moving/dragging windows horizontally
I get really annoying tearing while moving/dragging windows horizontally, there's no tearing if I move them vertically.
This is true for GNOME, XFCE, etc, so it's not desktop specific.
It is the same if I enable any compositor with xrender as backend (e.g Metacity, XFCE, etc)
Right now I'm using 185.18.04, but I tested with many 180.* and it's the same.
I have the driver with vsync enabled and I see no tearing with OpenGL composite managers (compiz/kwin).
Any idea what can be the problem?
My card is a Quadro FX 570M
