Default Xv overlaps with Composite

I just purchased a 7800gs, and Xv is overlapping windows if you move them over an Xv port. I do not get this with my 5200 in another machine. It's like the days of GL apps overlapping.

Is this supposed to happen?

I'll attach a bug log.

Xv is not expected to interact well with COMPOSITE currently, please see http://download.nvidia.com/XFree86/L...ppendix-s.html; this should change with a future NVIDIA Linux graphics driver release if run on Xorg >= 7.1, I believe.

OK thanks, but it is frustrating that my puny FX 5200 at work is actually usable and my rather expensive 7800gs overlaps.

Why are there multiple Xv paths? Is there an xorg.conf option to specify a path?

A geforcefx 5200 did video overlay (Xv) in hardware. Nvidia removed this in all geforce6/7 cards (except for early 6800 boards). On these recent cards Xv is emulated using simple 2d blitting. This is what can cause the difference.
